Modeling project

Finished several key aspects of the modeling project, where student groups take a real system and simplify it to its essential features.

• Rewrote the instructions to emphasize the goal is to improve some aspect of the system's performance, and that is why a quantitative model is a crucial tool, and that the model should be based on the key physics principles
• Changed the feedback form for the draft report to focus on the three main items the students should improve before the final. This should help the students improve their final version of the project report. The feedback form was adapted from "Tomorrow's Prof" newsletter
• Clarified rubric for the physics model so it more directly matches the steps strong project reports contain
  
• Adopted ISUComm's rubric for writing quality
