v1.2.1

Removes dependance on sphereogram package, as there was a circular dependency with that Python package.

v1.2

The main change is removing the special fast algorithm for alternating knots, which had a bug #17. Now both alternating and nonalternating knots use the same algorithm.

v1.1

Main changes:

• Computations can now be cleanly interrupted with Control-C.
• The UV=0 differential can be returned (suggested by Jonathan Hanselman).
• Bug fix: corrected overflow error for primes greater than or equal to 1297.

v1.0.2

Corrected nu for alternating knots when epsilon = -1
