----------------------------------+-----------------------------------------
Random simplicial complexes don't have the right number of vertices. From
the doctests:
sage: simplicial_complexes.RandomComplex(6, 2)
Simplicial complex with vertex set (0, 1, 2, 3, 4, 5, 6) and
15 facets
sage: simplicial_complexes.RandomComplex(6,12)
Simplicial complex with vertex set (0, 1, 2, 3, 4, 5, 6, 7)
and facets {(0, 1, 2, 3, 4, 5, 6, 7)}
In both cases, these should have 6 vertices, but they have 7 and 8
instead. Thus this method gives mathematically incorrect answers. The
attached patch fixes the problems.
