RandomFinders
=============
 
Allows quick and easy fetching of random records, or records in random order.
 
Simply pass the :random to the order in any finder method.
 
Examples
========
 
Find a random article
  Article.find(:first, :order => :random)
  
Randomize photos
  Photo.find(:all, :order => :random)
  
 
Caveat
======
 
This will not treat you nicely with large datasets.
