P = getSameCommunityProbability(W,nRep)

Given an undirected (weighted or binary) connection matrix
with positive and negative weights, the algorithm computes
the community structure nRep times and for each area pair,
computes the a posteriori probability that the 2 areas belong
to the same community. In fact, the community detection algorithm
makes use of heuristics, thus community partition may vary. For this
reason, it is suggested to use nRep > 50

Note: This code builds upon the function 'modularity_louvain_und_sign'
(using the Gómez, Jensen & Arena method implemented in the function),
which is part of the Brain Connectivity Toolbox
(https://sites.google.com/site/bctnet/).


INPUT

W : undirected (weighted or binary) connection matrix
with positive and negative weights

nRep : num. of repetitions of the community detection
algorithm


OUTPUT

P : Probability Matrix (probability that area i & j
were assigned to the same community)
