Added comments to new UI classes

If we weren't scrambling to get this done before Sprint 1 ends, I'd have
liked to spend more time cleaning up this code.

As it stands, we need this basic functionality to meet our minimum
requirements. We should revisit this code after our rush to finish
Sprint 1 ends and make the necessary changes to bring it up to our
standards.

Merge pull request #104 from BU-CS673/UI

Merging this myself since it's absolutely necessary for Sprint 1 and today's our last day for new features.
Pulled most recent Graphics changes into Production for Sprint 1 validation and testing. Modified Sprint1 test to use GL20.

Merge pull request #109 from BU-CS673/graphics

Graphics -> Canfield
Fixed 3 out of 4 UI warnings. Considering the 4th.

These were fairly harmless warnings, but in general code with warnings
should not be in production.
Typo fix: UserPrcoessContainer -> userProcessContainer

However, the comments imply that this code was created by a UI editor.
If that's the case, the value in the editor may need to be changed
directly, which is something that I don't have access to.
Changed Sprint 1 window title to "BUBOLO Sprint 1"
