Exceptions

Basic exceptions thrown by the library.

• RequestException - happens when the server responds with a 401 or 500 exception. 401 often means that a signature or parameter in either the form or url was incorrect or improperly formatted. 500 means that a request was not authorized and often times is because of a faulty user agent

• SleepyServerException - caused by a socket timeout by the Heroku servers because they automatically hibernate if there have not been enough requests over a certain amount of time
