Investigate gmpy usage #772

Original issue reported on code.google.com by gbtami on 24 May 2013 at 8:28

with gmpy is no more preformant than native python. Using profile command (thx 
Justin!) for benchmarking I got:

Hi. I maintain gmpy and found this issue via a Google search. I've released a 
new version called gmpy2 that contains some enhancements that may improve the 
performance relative to gmpy. There is a new mutable (!) integer type called 
xmpz that supports better bit access. Assuming X is an xmpz instance, you do 
the following:

X.iter_set() -> creates a generator that returns the bit positions that are set
X[7] = 1 -> set bit 8 (count starts with 0) to 1

Feel free to contact me if you have any questions.
