Valuate
=======
A portable application to easily associate a user valuation (rating, like etc) 
to any object, just on the basis of template tags. No configuration of existing 
models and views required. 


Installation
============

 - Run `python setup.py install`
 - Include 'valuate' in your installed apps settings. 
 - Add `(r'^valuate/', include('valuate.urls'))` to your main urls.py. 
 - Ensure you have a request context preprocessor added in the list of preprocessors
   or pass request varible context to views.

Let us say:

 - Good       4
 - Average    3
 - Bad        2
 - Poor       1

or
