NOTE: no longer using TastyPie due to issues with filtering on many-to-many relationships, trying out django-rest-framework which is already working out much better

api_view.py:
- new API views for django-rest-framework
- for SampleList, I had to override get_queryset to make it "look" like we are filtering on the model property 'name' but we're really building a bigger query

models.py:
- added 'name' property to show a simple concatenation of the parameter name and value type...used in the serializer for Sample

serializers.py
- new rest-framework serializers for Project, SampleParameterMap, and Sample

urls.py:
- commented out the TastyPie routes
- added django-rest-framework routes
