+%
+% Available class options
+% e.g., \documentclass[10pt,conference]{IEEEtran}
+%
+% *** choose only one from each category ***
+%
+% 9pt, 10pt, 11pt, 12pt
+% Sets normal font size. The default is 10pt.
+%
+% conference, journal, technote, peerreview, peerreviewca
+% determines format mode - conference papers, journal papers,
+% correspondence papers (technotes), or peer review papers. The user
+% should also select 9pt when using technote. peerreview is like
+% journal mode, but provides for a single-column "cover" title page for
+% anonymous peer review. The paper title (without the author names) is
+% repeated at the top of the page after the cover page. For peer review
+% papers, the \IEEEpeerreviewmaketitle command must be executed (will
+% automatically be ignored for non-peerreview modes) at the place the
+% cover page is to end, usually just after the abstract (keywords are
+% not normally used with peer review papers). peerreviewca is like
+% peerreview, but allows the author names to be entered and formatted
+% as with conference mode so that author affiliation and contact
+% information can be easily seen on the cover page.
+% The default is journal.
+%
+% draft, draftcls, draftclsnofoot, final
+% determines if paper is formatted as a widely spaced draft (for
+% handwritten editor comments) or as a properly typeset final version.
+% draftcls restricts draft mode to the class file while all other LaTeX
+% packages (i.e., \usepackage{graphicx}) will behave as final - allows
+% for a draft paper with visible figures, etc. draftclsnofoot is like
+% draftcls, but does not display the date and the word "DRAFT" at the foot
+% of the pages. If using one of the draft modes, the user will probably
+% also want to select onecolumn.
+% The default is final.
+%
+% letterpaper, a4paper
+% determines paper size: 8.5in X 11in or 210mm X 297mm. CHANGING THE PAPER
+% SIZE WILL NOT ALTER THE TYPESETTING OF THE DOCUMENT - ONLY THE MARGINS
+% WILL BE AFFECTED. In particular, documents using the a4paper option will
+% have reduced side margins (A4 is narrower than US letter) and a longer
+% bottom margin (A4 is longer than US letter). For both cases, the top
+% margins will be the same and the text will be horizontally centered.
+% For final submission to IEEE, authors should use US letter (8.5 X 11in)
+% paper. Note that authors should ensure that all post-processing
+% (ps, pdf, etc.) uses the same paper specificiation as the .tex document.
+% Problems here are by far the number one reason for incorrect margins.
+% IEEEtran will automatically set the default paper size under pdflatex
+% (without requiring a change to pdftex.cfg), so this issue is more
+% important to dvips users. Fix config.ps, config.pdf, or ~/.dvipsrc for
+% dvips, or use the dvips -t papersize option instead as needed. See the
+% testflow documentation
+% http://www.ctan.org/tex-archive/macros/latex/contrib/IEEEtran/testflow
+% for more details on dvips paper size configuration.
+% The default is letterpaper.
+%
+% oneside, twoside
+% determines if layout follows single sided or two sided (duplex)
+% printing. The only notable change is with the headings at the top of
+% the pages.
+% The default is oneside.
+%
+% onecolumn, twocolumn
+% determines if text is organized into one or two columns per page. One
+% column mode is usually used only with draft papers.
+% The default is twocolumn.
+%
+% compsoc
+% Use the format of the IEEE Computer Society.
+%
+% romanappendices
+% Use the "Appendix I" convention when numbering appendices. IEEEtran.cls
+% now defaults to Alpha "Appendix A" convention - the opposite of what
+% v1.6b and earlier did.
+%
+% captionsoff
+% disables the display of the figure/table captions. Some IEEE journals
+% request that captions be removed and figures/tables be put on pages
+% of their own at the end of an initial paper submission. The endfloat
+% package can be used with this class option to achieve this format.
+%
+% nofonttune
+% turns off tuning of the font interword spacing. Maybe useful to those
+% not using the standard Times fonts or for those who have already "tuned"
+% their fonts.
+% The default is to enable IEEEtran to tune font parameters.
+%

+% Available CLASSINPUTs provided (all are macros unless otherwise noted):
+% \CLASSINPUTbaselinestretch
+% \CLASSINPUTinnersidemargin
+% \CLASSINPUToutersidemargin
+% \CLASSINPUTtoptextmargin

+% \CLASSINFOnormalsizeunitybaselineskip (length)
+%
+% Available CLASSOPTIONs provided:
+% all class option flags (TeX if conditionals) unless otherwise noted,
+% e.g., \ifCLASSOPTIONcaptionsoff
+% point size options provided as a single macro:
+% \CLASSOPTIONpt
+% which will be defined as 9, 10, 11, or 12 depending on the document's
+% normalsize point size.
+% also, class option peerreviewca implies the use of class option peerreview
+% and classoption draft implies the use of class option draftcls

+% V1.6, we are now going to fine tune the interword spacing
+% The default interword glue for Times under TeX appears to use a
+% nominal interword spacing of 25% (relative to the font size, i.e., 1em)
+% a maximum of 40% and a minimum of 19%.
+% For example, 10pt text uses an interword glue of:
+%
+% 2.5pt plus 1.49998pt minus 0.59998pt
+%
+% However, IEEE allows for a more generous range which reduces the need
+% for hyphenation, especially for two column text. Furthermore, IEEE
+% tends to use a little bit more nominal space between the words.
+% IEEE's interword spacing percentages appear to be:
+% 35% nominal
+% 23% minimum
+% 50% maximum
+% (They may even be using a tad more for the largest fonts such as 24pt.)
+%
+% for bold text, IEEE increases the spacing a little more:
+% 37.5% nominal
+% 23% minimum
+% 55% maximum
+
+% here are the interword spacing ratios we'll use
+% for medium (normal weight)

+\def\@IEEEinterspaceMINratioM{0.23}
+\def\@IEEEinterspaceMAXratioM{0.50}

+% **** V1.3 ENHANCEMENTS ****
+% Itemize, Enumerate and Description (IED) List Controls
+% ***************************
+%
+%
+% IEEE seems to use at least two different values by
+% which ITEMIZED list labels are indented to the right
+% For The Journal of Lightwave Technology (JLT) and The Journal
+% on Selected Areas in Communications (JSAC), they tend to use
+% an indention equal to \parindent. For Transactions on Communications
+% they tend to indent ITEMIZED lists a little more--- 1.3\parindent.
+% We'll provide both values here for you so that you can choose
+% which one you like in your document using a command such as:
+% setlength{\IEEEilabelindent}{\IEEEilabelindentB}
+\newdimen\IEEEilabelindentA
+\IEEEilabelindentA \parindent
+
+\newdimen\IEEEilabelindentB
+\IEEEilabelindentB 1.3\parindent
+% However, we'll default to using \parindent
+% which makes more sense to me
+\newdimen\IEEEilabelindent
+\IEEEilabelindent \IEEEilabelindentA
+
+
+% This controls the default amount the enumerated list labels
+% are indented to the right.
+% Normally, this is the same as the paragraph indention
+\newdimen\IEEEelabelindent
+\IEEEelabelindent \parindent
+
+% This controls the default amount the description list labels
+% are indented to the right.
+% Normally, this is the same as the paragraph indention
+\newdimen\IEEEdlabelindent
+\IEEEdlabelindent \parindent
+
+% This is the value actually used within the IED lists.
+% The IED environments automatically set its value to
+% one of the three values above, so global changes do
+% not have any effect
+\newdimen\IEEElabelindent
+\IEEElabelindent \parindent
+
+% The actual amount labels will be indented is
+% \IEEElabelindent multiplied by the factor below
+% corresponding to the level of nesting depth
+% This provides a means by which the user can
+% alter the effective \IEEElabelindent for deeper
+% levels
+% There may not be such a thing as correct "standard IEEE"
+% values. What IEEE actually does may depend on the specific
+% circumstances.
+% The first list level almost always has full indention.
+% The second levels I've seen have only 75% of the normal indentation
+% Three level or greater nestings are very rare. I am guessing
+% that they don't use any indentation.
+\def\IEEElabelindentfactori{1.0} % almost always one
+\def\IEEElabelindentfactorii{0.75} % 0.0 or 1.0 may be used in some cases
+\def\IEEElabelindentfactoriii{0.0} % 0.75? 0.5? 0.0?
+\def\IEEElabelindentfactoriv{0.0}
+\def\IEEElabelindentfactorv{0.0}
+\def\IEEElabelindentfactorvi{0.0}
+
+% value actually used within IED lists, it is auto
+% set to one of the 6 values above
+% global changes here have no effect
+\def\IEEElabelindentfactor{1.0}
+
+% This controls the default spacing between the end of the IED
+% list labels and the list text, when normal text is used for
+% the labels.
+\newdimen\IEEEiednormlabelsep
+\IEEEiednormlabelsep 0.6em
+
+% This controls the default spacing between the end of the IED
+% list labels and the list text, when math symbols are used for
+% the labels (nomenclature lists). IEEE usually increases the
+% spacing in these cases
+\newdimen\IEEEiedmathlabelsep
+\IEEEiedmathlabelsep 1.2em
+
+% This controls the extra vertical separation put above and
+% below each IED list. IEEE usually puts a little extra spacing
+% around each list. However, this spacing is barely noticeable.
+\newskip\IEEEiedtopsep
+\IEEEiedtopsep 2pt plus 1pt minus 1pt
+
+
+% This command is executed within each IED list environment
+% at the beginning of the list. You can use this to set the
+% parameters for some/all your IED list(s) without disturbing
+% global parameters that affect things other than lists.
+% i.e., renewcommand{\IEEEiedlistdecl}{\setlength{\labelsep}{5em}}
+% will alter the \labelsep for the next list(s) until
+% \IEEEiedlistdecl is redefined.
+\def\IEEEiedlistdecl{\relax}
+
+% This command provides an easy way to set \leftmargin based
+% on the \labelwidth, \labelsep and the argument \IEEElabelindent
+% Usage: \IEEEcalcleftmargin{width-to-indent-the-label}
+% output is in the \leftmargin variable, i.e., effectively:
+% \leftmargin = argument + \labelwidth + \labelsep
+% Note controlled spacing here, shield end of lines with %
+\def\IEEEcalcleftmargin#1{\setlength{\leftmargin}{#1}%
+\addtolength{\leftmargin}{\labelwidth}%
+\addtolength{\leftmargin}{\labelsep}}
+
+% This command provides an easy way to set \labelwidth to the
+% width of the given text. It is the same as
+% \settowidth{\labelwidth}{label-text}
+% and useful as a shorter alternative.
+% Typically used to set \labelwidth to be the width
+% of the longest label in the list
+\def\IEEEsetlabelwidth#1{\settowidth{\labelwidth}{#1}}
+
+% When this command is executed, IED lists will use the
+% IEEEiedmathlabelsep label separation rather than the normal
+% spacing. To have an effect, this command must be executed via
+% the \IEEEiedlistdecl or within the option of the IED list
+% environments.
+\def\IEEEusemathlabelsep{\setlength{\labelsep}{\IEEEiedmathlabelsep}}
+
+% A flag which controls whether the IED lists automatically

+
+% V1.6, we need to make \footnotesep responsive to changes
+% in \baselineskip or strange spacings will result when in
+% draft mode. Here is a little LaTeX secret - \footnotesep
+% determines the height of an invisible strut that is placed
+% *above* the baseline of footnotes after the first. Since
+% LaTeX considers the space for characters to be 0.7/baselineskip
+% above the baseline and 0.3/baselineskip below it, we need to
+% use 0.7/baselineskip as a \footnotesep to maintain equal spacing
+% between all the lines of the footnotes. IEEE often uses a tad
+% more, so use 0.8\baselineskip. This slightly larger value also helps
+% the text to clear the footnote marks. Note that \thanks in IEEEtran
+% uses its own value of \footnotesep which is set in \maketitle.

+% \IEEEeqnarraybox is like \IEEEeqnarray except the box form puts everything

+% V1.6 we create hooks for the optional use of Donald Arseneau's

+% citation numbers and auto detection of 3 or more entry "ranges" -
+% all in IEEE style: [1], [2], [5]--[7], [12]
+% This also allows for an optional note, i.e., \cite[mynote]{..}.
+% If the \cite with note has more than one reference, the note will
+% be applied to the last of the listed references. It is generally

+% \IEEEauthorrefmark{} produces a footnote type symbol to indicate author affiliation.
+% When given an argument of 1 to 9, \IEEEauthorrefmark{} follows the standard LaTeX footnote
+% symbol sequence convention. However, for arguments 10 and above, \IEEEauthorrefmark{}
+% reverts to using lower case roman numerals, so it cannot overflow. Do note that you
+% cannot use \footnotemark[] in place of \IEEEauthorrefmark{} within \author as the footnote
+% symbols will have been turned off to prevent \thanks from creating footnote marks.
+% \IEEEauthorrefmark{} produces a symbol that appears to LaTeX as having zero vertical
+% height - this allows for a more compact line packing, but the user must ensure that
+% the interline spacing is large enough to prevent \IEEEauthorrefmark{} from colliding
+% with the text above.

+% \IEEEPARstart
+% Definition for the big two line drop cap letter at the beginning of the
+% first paragraph of journal papers. The first argument is the first letter
+% of the first word, the second argument is the remaining letters of the
+% first word which will be rendered in upper case.
+% In V1.6 this has been completely rewritten to:
+%
+% 1. no longer have problems when the user begins an environment
+% within the paragraph that uses \IEEEPARstart.
+% 2. auto-detect and use the current font family
+% 3. revise handling of the space at the end of the first word so that
+% interword glue will now work as normal.
+% 4. produce correctly aligned edges for the (two) indented lines.
+%
+% We generalize things via control macros - playing with these is fun too.

+% the actual ("internal") command is stored as \\commandname
+% (accessed via \csname\string\commandname\endcsname )
+% the "external" command \commandname is a macro with code to determine

+% we would have to save and restore \\commandname as well. But, if LaTeX
