Improve Drive.java documentation

[cuttestkittensrule]

Currently, there is not a lot of documentation for the drive.java method that takes a ChassisSpeeds, and why we need to use ApplyFieldSpeeds instead of ApplyRobotSpeeds. (will be merged in with #63)
Finaly, the looks stupid comments are not very descriptive, and can be improved.

I am currently working on adding some more documentation to the #63

Some documentation was merged in #63. If it is sufficient, we should close this issue
