So marking functions like `add_markings()` can be directly called as methods on
SDO/SRO classes. Note that they return new versions of the objects
because objects are immutable.
Also remove package and module names from classes and functions.
Also remove stix2.base from docs. We hide all private classes and
functions from the docs, so the only thing the documentation for base
included was STIXJSONEncoder.
- Test markings functions with both dictionaries and our _STIXBase-derived
classes as input.
- Slightly improve test coverage.
- Drop Python 2.6 support.
This required refactoring parts of the library. Code in __init__.py
merged into bundle.py, which was renamed core.py. Code in other.py was
merged into common.py.
Fixes#40.
- Typos in Attack Pattern tests
- Put MarkingDefinition, ExternalReference, and KillChainPhase together
in a file for objects that aren't SDOs or SROs
- Create utility function to return dictionary from string or
file-like object
- Put off testing parsing Cyber Observable Objects until a later commit
- Update ReferenceProperty to allow specifying a particular object type
- Update ListProperty and add SelectorProperty
- Add description to Relationship
