docs/
- replace tastypie with djangorestframework in the install doc
models.py:
- don't try to open a sample_file if it's already open, and if was closed, open it and close it back...leave things the same as how they arrived
- temp files over 2.5MB are still getting stuck in /tmp tried overriding save to see if we can determine whether the sample file is in /tmp and what it's name is

api_views.py:
- commented out the post override in SampleList, seems to cause some issues 1 in 10 times resulting in the sample parameters not getting saved and the client gets an empty HTTPResponse....investigating this with the django-rest-framework and django-users Google group
- also commented out the override of the dispatch method in the LoginRequired mixin...was used to make API views CSRF exempt but the api views are exempt by default so this isn't needed
settings_sample.py:
- make sure to set FILE_UPLOAD_TEMP_DIR (on Macs this doesn't seem to get set)
- add INTERACTIVE_DEBUG setting...we'll catch this in wsgi.py to setup interactive debugging...useful for apache2ctl -X (apache debug mode)

wsgi.py:
- if INTERACTIVE_DEBUG is True, setup the wsgi_application to get wrapped in our custom Debugger class
