APSG 1.0.1 release

What's new in this release

• density_lookup method implemented for StereoNet.grid
• Stress tensor sigma* properties using inverted order of eigenvalues
• render2fig method of StereoNet implemented
• vector-like objects are not iterable, so properly render in pandas

APSG 1.0.0 major release

APSG has been significantly refactored from version 1.0 and several changes are
breaking backward compatibility. The main APSG namespace provides often-used
classes in lowercase names as aliases to PascalCase convention used in
modules to provide a simplified interface for users. The PascalCase names of
classes use longer and plain English names instead acronyms for better
readability.

See documentation for further details.
