The gist of the commit are a few improvements in the
create action, where:
* long boolean statemenst have been wrapped in smaller more readable
methods.
* the 3rd party user info creation has been extracted (still in controller)
* a small helper method for creating a new user from params (to reduce
visual clutter)
* specs have been added where I came across untested methods/branches
Other changes are more trivial like formatting and whitespace fixes.
Hope this helps. Regards.
