Zachary Pincus 56a5cadde2 Performance fix for heap; correctness for _mcp
(1) normalize_indices in _mcp.pyx should convert indices to ints: fixed
(2) huge (order of magnitude) performance problems in heap.pyx from changing
lines like:
ii = (i-1)/2 # CalcPrevAbs

to:
ii = (int)(i-1)/2 # CalcPrevAbs

for some reason,  the latter goes through the python division machinery!
However, the former is invalid for cython >=0.12, so the proper solution is:
ii = (i-1)//2 # CalcPrevAbs
