[NET-243] New plot in mlapp file

[pollaro]

This is the all-in-one trimatrix plot with an mlapp file.

I really hate that this thing works better.
Here's some changes:

• MATLAB has enum support. Unfortunately, when a variable is passed from the front -> back of an mlapp, it's converted to string. So, that's why all the enum values are strings now.
• Have scaling and such go with onChange actions. The apply button is really only needed for a few options. If the plot doesn't change immediately, it's probably one of them.
• That's about it. Most of the code is the same just changing obj -> app. Also, removed network atlas as a property from the obj. There's no reason to carry it over since it's in something else already
