#89 Add support for @Generated

[Daniel Holmes]

It would be nice to be able to configure to ignore code coverage for generated code. Using the Java @Generated (http://java.sun.com/javase/6/docs/api/javax/annotation/Generated.html) annotation seems to now provide for a standard method for doing so. Since the value attribute of this annotation is designed to allow for specific generator names to be provided, it would be useful for this support to allow for the configuring of code generated from specific generators to be included/excluded via the filtering mechanism.
