Modified folder structure, Removed dependency on "Tools"-addon in example

Just restructured the folders of the addon so it is compatible with the [ofx commandline tool](https://github.com/prusnak/ofx) and the [ofx xcode plugin](https://github.com/admsyn/OFPlugin).
I also removed the dependency to [vanderlin/Tools](https://github.com/vanderlin/Tools) from the example to make it easier to give the addon a quick try.

Tested on Mac OS X 10.9, Xcode 5.1, openFrameworks 0.8
