Reviewing @imsamurai's fork there are some cleaner implementations I would like to merge back into this fork for greater code-clarity and efficiency.
I'm still not sure where I sit on the approach to OAuth and field mapping as the field mapping seems a bit complex for me to easily grasp at the moment and the OAuth integration is intended to allow REST queries.
Need to poke around a bit more to see if Opauth credentials are supplemented into RESTful requests for further merger consideration.
