This updates almost all the camelCase function names found in codebase

to use our standard naming convention. In some places, it also updates

docstrings to be more useful and clear. This will help contributors to

see good (or at least better) examples of how their tests and functions

should look.
This does not update any assert* function names, nor does it update

anything in the webapi codebase (since this is handled by another

change).

Unit tests pass.
