SAMDL: Command Line features in app

[ItsEasyActually]

There's several tools that are command line based that we could probably add in the same functionality to SAMDL for ease of use. Most notable are these three:

• ModelRelabeler
• SplitShapeMotion
• BuildShapeMotion

In general, the command line tools are great for having a quick to use app to do whatever we need it to, but having these functions in a "one stop shop" so to speak would benefit users overall.

This list may grow if we end up with more tools that work on the models outside of SAMDL.

If/when we get this stuff is added, we can close this.
