If you use extend instead of include, the methods in the module should
be seen first. Extend operates on instances, not classes, tho, so
you'll have to call extend in your initialize.

Alternately, if you make a subclass and then use include in the
subclass, I believe that will also utilize the module version. Not
sure how that might interoperate with rails.
