v0.2.0 progress
 * Commented out eland_result table as it is not being used by either site and Stanford has implemented something that is probably more useful, so we will like import that.
 * Person has been renamed to UserProfile and has been intergrated with the user profiles feature of Django (http://www.djangobook.com/en/1.0/chapter12/#cn222), which allows you to get access to the "profile" information by using user.get_profile().
 * Added Lab which just contains a name... This will be used to implement user/lab level access to Flowcell/Library information.
