Helper class to manage attachment of metadata to other class objects.
Since in the purest sense metadata means "data about data" it is often useful to attach the metadata directly to the data which it informs. This helper class provides a simple interface for doing just that.
Use it as a mixin on any class to which metadata is to be attached. Implement the abstract methods to access the metadata from wherever your class wishes to store it.
