Added another variant of periodicity test. 
Knotkit can read the list of knots to test from a file.

203477c3a8 First shot at periodicity congruences 
Verification of Przytycki's congruence works fine, however there are
some small modifications that could be made.

The, naive, approach to the verification of periodicity congruence for
the Khovanov polynomial didn't work. There are just too many cases to
check. Generation of all of them can exhaust the memory.

66813d4a15 Added some C++11 features to classes Z and Q 
Z and Q use now smart pointers for storing their internal
implementations, which were changed to use mpz_class and
mpq_class. New implementation uses copy on write. Moreover, I added
moving semantics for these two classes.
