Small bugfix.
Added norm type to fortran interface.
Fixing multiply counts in SpAMM.
Fixing flop count in SpAMM.

For a small water system I correctly reproduce the flop counts now for SpAMM
SP2 and BCSR SP2. I still need to work on adding fixed blocksize for SpAMM,
i.e. SpAMM_SP2 should not use a fixed chunk tier but choose the one that gives
a fixed blocksize.
Fixed flop counting.

For a single water molecule the counting agrees now between BCSR and SpAMM.
Small fix to compare_forces.py
Bug fix.
Added hack to fix apparent compiler bug.
