v3.0.0

This update adds a great deal of new functionality and stability.

The rupture model has been overhauled for stability. Event slip matrix solutions have been removed in favor of a purely cellular automaton method.

Faults are now separate objects from sections. This allows ruptures to spread between sections belonging to the same larger fault, while allowing each section to have its properties defined independently.

Many new PyVQ plotting and filtering options have been added.

Several major and minor bugs have been fixed.
