ActionHelper
============
 
ActionHelper is a Rails plugin that allows you to create view helper modules 
for specific actions or templates, as opposed to the controller-wide helper 
facility Rails provides.
 
 
Example
=======
 
There are currently three ways to get action-specific helpers mixed in.
 
module SuperHawtnessHelper end
module ExampleSweetnessHelper end
 
class ExampleController < ActionController::Base
  include ActionHelper
  
  helper SuperHawtnessHelper, :only => :hawtness
  
  def hawtness
    # Only this action will get SuperHawtnessHelper since the #helper call 
    # above used the :only option.
  end
  
  def sweetness
    # This action will get ExampleSweetnessHelper because the name matches 
    # the controller name and action name concatenated.
  end
  
  def supercool; action_helper ExampleSweetnessHelper
    # This action will get ExampleSweetnessHelper because it just said so.
  end
end
 
 
TODO
====
 
* Allow an action to declare what helper(s) it wants by name in addition to 
  passing the module itself (same as Rails does).
* Experiment with keying off the template name rather than the action (to deal 
  with actions that might render alternate templates)
* Build up a master module for each action so we're not doing so many extends 
  on every request.
* Get things self-contained so specs (including controller specs) run without 
  a surrounding Rails app.
