Merge lp:~cezary-bartosiak/gephi/generator-plugin into lp:~gephi.team/gephi/0.8

[Cezary Bartosiak]

Several generators implemented:

a) Erdős-Rényi model in two versions G(n, p) and G(n, m)

b) Alpha and Beta models of Watts and Strogatz

c) Kleinberg model

d) Barabási–Albert model in 4 versions: basic, generalized generator with probabilities of adding new edges and rewiring existing ones, simplified models: A (uniform attachment) and B (no growth)

e) Balanced Tree

[lp:~cezary-bartosiak/gephi/generator-plugin]

2038. By Cezary Bartosiak on 2010-12-17

* added torus based parameter for Kleinberg model
