Title: Adding the functionality to have a OR operated find.

E.g.
collection.where({key:value); will still return the collections where key equals value. I have added the option:
collection.where({key:[value1,value2]}) now it will return all models where key has either value1 or value2.

I've added this because I needed it for a faceted search project.
