the edge "name" is its key or id (i can't remember which we use now as
it is relatively obscure)  e.g.  a->b [id=hello]   a->b [id=goodbye]


I implemented agsplice to move an edge from one node to another.
it also would also allow dangling edges, e.g. move an edge to a
NIL endpoint, but there are a lot of details to consider, and exercising
this could potentially break code that assumes a graph is well formed.


all this has to be ported to the new library libCgraph too.
