views.py:
- fixed some PEP formatting issues, mainly long lines and not having 2 blank lines for class definitions
httplib_get_example.py
- added rest client example using httplib, since it's a bit easier to use than the urllib/urllib2 combo
- using Basic Authentication in this script

edit_sample.html:
- new template for editing a sample, pretty much just allows you to change the visit

view_subject.html:
- added link to edit_sample view

api_views.py:
- enabled basic authentication in addition to the session authentication for rest client access.
- should probably turn off session authentication for rest views
- change SampleList to a ListCreateAPIView to allow creation of new samples via rest...yeehoo, works with one line change!

forms.py:
- new form for editing samples

serializers.py:
- need to make some fields read-only else they show up in the post form and become 'required' fields

urls.py
- new route for edit_sample view

views.py:
- new view 'edit_sample'

base.html & bootstrap.css:
- was playing with some breadcrumb stuff, but doesn't seem useful...may re-visit if people complain about navigation usability
