Ryan McKern 42743614cb (MODULES-905) Add bool2str() and camelcase() for string manipulation
Python likes to have its constants Capitalized, and the capitalize
function only understands strings... so I shave a yak.

bool2str will convert a boolean to its equivalent string value,
and camelcase extends on uppercase & downcase to convert an underscore
delimited string into a camelcased string.
