----------------------------+---------------------------------
Some Graph functions are not made to handle non-simple graphs, i.e. graphs
containing loops or multiple edges. This ticket adds necessary exceptions
from place to place, hoping no error remains ignored.
The exception advises the user to remove loops/multiple edges from his
graph and try again (and to update the function if he thinks that not
supporting non-simple graphs is a mistake) `:-P`
This has been reported on sage-support fairly recently [1], and thousands
of times before. Past time to deal with those wrong answers `:-/`
