This is a minor nit, but for a user facing interface I don't think we
should export abbreviated variable names. I'll apply this with the
following fixups:

s/iteration_nbr/iterations/
s/Iteration number/Iterations/

...as well as a fix for the checkpatch violation of initializing a static to 0.

Dan
