Fixes #399 .
stix2/__init__.py currently does a star-import from stix2.v20. Unfortunately that brings in a "base" symbol which becomes stix2.base, and hides the actual stix2/base.py module. This PR adds
__all__
s to the v20 and v21 modules which explicitly lists what symbols should be imported, so we don't get "base" by mistake from them.(Impl note: the text block split() technique makes it easier to keep the __all__ lists up-to-date, because you can just copy-paste the symbol lists from the imports above.)
