* implement loba_* algorithms (start with some trivial one)
* add loba algorithm selection (-a number ?)

* fix process::run when load is 0
   -> wait for a message...
   -> how does it work with opt::bookkeeping ???

* implement automatic process topology 
   (line, ring, star, btree, clique, hypercube, etc..)
