The start video stream method in the common module wasn't using its camera argument, so actually made the argument useful.

Added a module to test the authentication manually with some pictures, as well as improved the way the authentication module works.

Realized that there were some problems with the authentication and common modules, so fixed them here.

Made some small changes to certain things that wouldn't be necessary in common anymore. Although, this will break some of the stuff that I was attempting to do before.

Worked on the new deep learning model, but now realizing that it won't really work well for our application, so I'm switching to the older way of doing it.

The new register user, using custom methods, appears to work nicely from basic testing. Will continue with other things now.

Now using the cv2 video stream instead of the imUtils one, since it seems to be a little less latent.

The registering and authentication of users now works together nicely. Will continue with making it more efficient and integration with the react side.

The register user functionality isn't quite working, doesn't save to the database properly. Will continue working on this.

Still preparing for user registration stuff. Made some changes to
authentication to make some of its general methods available for the
user registration module as well.
