Feature/infinite w

[evanberkowitz]

Provides the ability to do W=∞ simulations. This required

• Substantial documentation updates.
• Updating generators to allow for real-valued v (in which case W=2π).
• Harmonizing the tallying point of the worms.
• Updating observables.

This was tested by running example/no-vortices.py for a variety of lattice sizes at the self-dual κ. One example is

Getting such precision also required allowing the hammer to run not just 1 worm per sequential iteration but a large number.
