Changes

1.0.0 (unreleased)

First PyPI release.
Add support for Python 3.
Drop support for externalizing to plists. See #21
Reach 100% test coverage and ensure we remain there through CI.
Introduce nti.externalization.extension_points to hold hook functions. Move the Pyramid integration there (and deprecate that). Also move the NTIID support there (but the old name works too). See #27
