v0.2.2 - Sphinx AutoDoc; Improved List, Union, and Instance Properties

New Features

• Sphinx documentation generated for HasProperties classes in the metaclass based on the class's properties

Minor Changes:

• required properties may now have default values. On validate, a required property cannot be None or undefined
• assert_valid ensures HasProperty classes are valid
• List:
  • List properties are now lists of a given property type. A HasProperties class can also be provided - this is coerced into an instance property of that class.
  • validation errors raise list errors rather than errors of the property type
  • assert_valid validates HasProperties instances only
  • list now has min/max length property
• Union:
  • Similar to list, Union now allows HasProperties classes, coercing them into Instance properties
  • Union was moved to base from basic
• Uid:
  • assert_valid ensures the uid has not been tampered with
• Additional testing of the new features
• Improved docstrings
