CCLE-3993 - Removed "ucla" from code entirely

In order to open-source the project, ucla has been removed
from all:
- variables
- classes
- functions
- database tables
- strings
- files
- comments

The only mention of UCLA is in the README file (in the
credits, as well as downloads - because the repository
still has our name). Also, there is a copyright tag
at the top of every file:
