// Mixes in a to_conditions method to ActiveRecord::Base. Converts the attributes of an AR object to a
// ActiveRecord::Base#find :conditions hash. Useful for comparing AR objects, especially when looking for
// duplicates.
// E.g.
//
// if not Post.find(:all, :conditions => my_post.conditions).empty?
// puts "Duplicate found"
// end
