Returns a sparse incidence matrix 'mInc' according to the adjacency matrix 'mAdj'. The edge ordering in the incidence matrix is according to the order of adjacent edges of vertices starting from the 1st vertex, i.e. first edges coincide with first vertex, next edges coincide with second vertex, etc.
If the graph is directed, the incidence matrix mInc contains -1s, indicating an "in-going" edge, and 1s indicating an "out-going" edge.
If the graph is undirected, the incidence matrix mInc contains only 1s.
