Simplere

In several dot-releases, have added support for Travis-CI cloud-
based continuous integration testing, Sphinx-based documentation,
and readthedocs.org hosted documentation. The Travis bit has
required a separate Github repository be created. It is managed
out of the same development directory, overlaying the existing
Mercurial / Bitbucket repo. So far, that has caused no problems.

Documentation somewhat improved.

Cleaned up source for better PEP8 conformance

Bumped version number to 1.0 as part of move to `semantic
versioning <http://semver.org>`_, or at least enough of it so as
to not screw up Python installation procedures (which don't seem
to understand 0.401 is a lesser version that 0.5, because 401 > 5)
