Paper: Project-based introduction to scientific computing for physics majors (Jennifer Klay)

This is the first draft of the paper for my SciPy talk.  It still needs some work.  I will finish the final draft later this week after finals are graded and exams are submitted.  Let me know if you have any questions.  Thanks!
The `i` in `IPython` should be capitalized here and elsewhere. This keeps us away from sounding like an Apple project ;-)
