Iterates over all triangles incident to a given vertex in a circular manner. Thereby, counterclockwise is the positive direction.

inlineexplicit 
pPnt_  is the vertex whose incident triangles can be visited with the iterator 
The iterator will start at an arbitrary triangle

pPnt_  is the vertex whose incident triangles can be visited with the iterator 
pTr_  is the triangle where the iterator will start

Dereferencing the iterator yields a pointer to the triangle to which the iterator points.
