It is not redundant. In the demonstration, indeed it may appear so, however consider
what happens if I want to throw an exception from the end-implementation. I would be
throwing an Exception, and not an EmberException.

As well, I find it good practice to catch Exception if there is a chance it MAY be
thrown.

Additionally, so far as I know, every derived Exception class has to extend
Exception. Correct me if I'm wrong, but I do do believe that is the case.
It's all about the polymorphism.

Finally, I should note that I am further developing this implementation (of
course). All that array crap is going to be garbage soon. Ugly, and resource
intensive.

Does your EmberException extend Exception? If so, remove the catch( EmberException )
block as it is redundant and not needed. EmberException would be of type Exception.
