* First commit to gather feedback on class design.

* Changed set_*/get_* pattern to use_*/to_*

* Add generic_linear() as a separate module temperature function and adjustments to doc strings.

* Add tests.

* Minor test edits.

* One more test to achieve 100% coverage (hopefully).

* Some formatting, docstring development.

* Try to update sphynx.

* Try sphynx again.
