			% Name: mexCountConnexComponents
			%
			% Description: mexCountConnexComponents counts the number of connected
			% components of the subgraph of G corresponding to set of nodes
			% in N. In other words, the subgraph of G by removing from G all
			% the nodes which are not in N.
			%
			% for a graph G with \|V\| nodes and \|E\| arcs,
			% G is a double sparse adjacency matrix of size \|V\|x\|V\|,
			% with \|E\| non-zero entries.
			% (see example in test_CountConnexComponents.m)
			% N is a dense vector of size \|V\|. if N[i] is non-zero,
			% it means that the node i is selected.
			%
			%
			% Inputs: G: double sparse \|V\| x \|V\| matrix (full graph)
			% N: double full \|V\| vector.
			%
			% Output: num: number of connected components.
