This is a shortcut for raise:format: method and makes exception creation code much less verbose. As we don't
use specialized exception names, this makes sense...

Discussion
This is useful for converting NSErrors into NSExceptions. The method allows the client to pass in additional
context information which further aids diagnosting the exact reason for the exception. If no context information
is desired, pass nil and only error information is used for formatting. As exception message can become quite
verbose, it is split into several lines to make the output more readable.
