Mesh iterators (me.faces, me.edges, me.verts, face and edge iterator) store the iterator progress in the python object.
This made nested loops with the same python object mess up.
eg-
faces= me.faces
for f1 in faces:
for f2 in faces:
print f1.index,f2.index

This didnt work, fixed by initializing the iter value at -1, so any greater value will create a new BPyObject with its own iter value.
once iteration is finished, its set back to -1.

Also made face and edges iter value a char instead of an int to save some memory.
