Imported both jQuery and Bootstrap to the project

Bootstrap requires jQuery.  They are included in both app/ and
testapp/, and all tests still pass.
Replace link PNG with Bootstrap's link Glyphicon
Split test app page into HTML/Source tabs
Adding some simple CSS tools to the test app
Gave test app interface for running code user inputs

Source view is updated as user runs code, to reflect most recent state
of main div
Test app stores history of model state and code run
Adds test app buttons to mark states right/wrong

Also updated plan, as I get closer to later parts of it
