Returns a sparse adjacency matrix 'mAdj' according to the incidence matrix 'mInc'. The rows in the incidence matrix must represent the edges, while the columns the vertices.
Function can handle directed graphs with incidence matrix containing -1s, indicating an "in-going" edge, and 1s indicating an "out-going" edge.
