This PR adds some unit tests and documentation for some previously undocumented column mappings attributes: set_value_column_a, set_value_column_b, override_column_a, override_column_b, and override_transforms. These attributes greatly increase the flexibility of the column_mappings section, so it's important to document them so that users know that they're available.
The changes in the docs/ directory are automatically generated from the sphinx-docs/ directory.
Closes #118.
