Overview

This class allows obsevers to register a single block rather than implementing public observer methods (which can get messy and unnecessarily pollute the public API of the class)

Each registered block will be called with the following arguments:

1) The notification name (or the method name to be called) 2) The sender of the notification 3) The notification parameters.
