-* This class contains the implementation of the Barabasi-Albert model
-* of growing scale free networks. The original model is described in
-* <a href="http://arxiv.org/abs/cond-mat/0106096">http://arxiv.org/abs/cond-mat/0106096</a>. It also contains the option of building
-* a directed network, in which case the model is a variation of the BA model
-* described in <a href="http://arxiv.org/pdf/cond-mat/0408391">
-http://arxiv.org/pdf/cond-mat/0408391</a>. In both cases, the number of the
-* initial set of nodes is the same as the degree parameter, and no links are
-* added. The first added node is connected to all of the initial nodes,
-* and after that the BA model is used normally.
