Develop

You don't have to stop the show because of the error, but it does need to be dealt with.  This library can decide how to deal with the error, or it can pass it back to the developer for them to handle how they see fit.  But the error should definitely not be swallowed and ignored.

In the case of `authenticateApiRequest` the error contains a LOT of useful information that should be passed back to the end-user who made the HTTP request of the endpoint (token has expired, invalid credentials, invalid scopes, etc).  So that error should be passed back to the original requestor and the status code preserved as the HTTP response status.

In the case of `getAccount` the error can indicate invalid credentials (need to tell the end user), a disabled account (probably want to let the developer handle this one), or a problem with the Stormpath API (should be handled gracefully, probably with intervention from the developer)
