Update dependency to ember-data beta.11
rename serializer to be inline with newer ember-data
determineRelationshipType is now a method on record.constructor.
data.relationshipKey does not work with newer ember-data, use mapBy instead.
Remove failing test for now
Make sure group is also async.
Update function parameters
We are serializing hasMany and not a belongsTo relationship.
Fix findMany, honors adapter.coalesceFindRequests flag and generates the proper URL

Some edge cases are still not tested, specially function splitGroupToFitUrl, which is probably not returning the correct url for tastypie. As long as your findMany doesn't hit the 2048 characters mark, you are safe to use this.
