NDI_DOCS2GRAPH - create a directed graph from a cell array of NDI_DOCUMENT objects
[G,NODES,MDIGRAPH] = ndi.database.fun.docs2graph(NDI_DOCUMENT_OBJ)
Given a cell array of ndi.document objects, this function creates a directed graph with the
'depends_on' relationships. If an object A 'depends on' another object B, there will be an edge from B to A.
The adjacency matrix G, the node names (document ids) NODES, and the Matlab directed graph object MDIGRAPH are
