Feature/Point Collection System

[katedmc]

Description

What

New feature: A point system for the TBB.

Why

This gives users to opportunity for feedback and reinforcement for learning from the TBB

How

The point system is built directly into the Authoring App Questions. The score the user gets is tracked
by answers the questions correctly. An offset is tracked when the user gets a question wrong. The total
number of questions is calculated from the score and offset.
The second part of the point system is outputting the score and total values. These items have been
added to the items menu. The output is just the number corresponding either value. The way the
information is communicated in the scenario is left up to the user of the Authoring App.
