  Log Message:
  -----------
  Add an option for unrolling loops up to a factor.

Currently, there is no option to allow for unrolling a loop up to a specific factor (specified by the user).
The code for doing that is there and there are benefits when unrolling is done  to smaller loops (smaller than the factor specified).
