In Vertex conf pqt case
we can have infinite vertex even if p is not endpoint of q
and so previous assertion is removed, and the case is included
when p is not end point of q, and we check for the conflict
due to insertion of t
In Finite edge conf for p,q,t,sgn functor
we removed the assertion of p is endpoint of q,
and included the case when p is not end point of q
and check for the conflict with t
This solves the test case h2.cin
