* This class handles a lower level type of access to App.net. It's ideal
* for command line scripts and other places where you want full control
* over what's happening, and you're at least a little familiar with oAuth.
*
* Alternatively you can use the EZAppDotNet class which automatically takes
* care of a lot of the details like logging in, keeping track of tokens,
* etc. EZAppDotNet assumes you're accessing App.net via a browser, whereas
* this class tries to make no assumptions at all.
