This function creates a directed lattice in d=2 where edges go up or right.
The ig.Graph.Lattice function does not appear to create directed graphs well.
Use plot_graph to test with a small N.
Returns: a tuple (g,l) where g is an igraph object, and l is an igraph layout
directed=True produces a directed lattice with only up/right paths. Currently the other functions cannot handle the undirected lattice
noigraph_gen=True does not generate the igraph object. This is mostly used for debugging.
return_layout_as_object=True returns the second return value as an igraph object
graph_shape='rectangle' or 'triangle'
If chosen to be a triangle, helps cut down on computation time for limit shape computations. This is because you do not want to limit shape to be truncated.
igraph does not check for uniqueness when adding vertices by name.
Oct 25 2017 The for loop in this function is very slow. An iterator that yields is definitely better since the for loop is run by the igraph creation routine.
Oct 24 2017 This is a fairly inefficient function. Probably easier to add vertices by generating a list of names first. noigraph_gen simply retuns edges and vertices
