Description
This is a reimplementation of the IntervalGraph()
constructor to allow repeated intervals in the list of intervals. The input is a list of intervals. The output is a graph whose vertices are numbered 0 through n-1 (where n is the length of the list). Vertices u and v are adjacent iff the u'th and v'th intervals in the input list intersect. The intervals associated with these vertices are saved with the graph using set_vertex
and can be retrieved later using get_vertex
or get_vertices
.

Doc string changes are fine. Thanks, Nathann.

Two short modifications in the docstring... One to use the ".. NOTE" environment, and another one to propagate the warnings to RandomInterval?

As usual, positive review to your patch ! It's left to you to judge mine
