ActsAsRenderable
================

Allows ERb code stored in ActiveRecord to be rendered as by ActionView.

In your action code inside a controller you can use render_model() to tell 
the controller which method of an object as the code to render, rather 
than the contents of a template file.

		def show
			@person = Person.find(@params[:id])
		  render_model :object => @person
		end
		
By default @person.show will be rendered, but you can override this
like so:

    render_model :object => @person, :method => :show_view

Optionally, in your model code, you can define which method should be 
used to render which controller/actions.

		class Person < ActiveRecord::Base
			acts_as_renderable :method => :show_view, 
		  	                 :controller => 'example', 
		    	               :action => 'show'
		    	               
		  def show_view
		  	"<div>#{show}</div>"
		  end
		end

So you can put this in ExampleController:

		def show
			@person = Person.find(@params[:id])
		  render_model :object => @person
		end
    
and the controller knows to use :show_view instead of :show for this
action.  render_model() responds to :layout and :status normally.

DISCLAIMER: I know this is a hideous violation of MVC rules, but it 
  it might be useful to someone at some point.  Besides, I learned 
  a lot about plugins while writing it.
