According to the Agile Development book, in ch 17 on helpers it says:
"A helper is simply a module containing methods that assist a view. Helpers are output-centric"
I expect to refactor a lot of code into a few library classes that really have nothing to do with views or output. This would be mostly math related functions. In the past I've just stuck another class definition at the end of a controller, but I'm pretty sure thats NOT the rails way to do it.
Do these libraries really belong in app/helpers or am I just reading too much into the books definition of a helper?
