Lab 1 and .gitignore.
Modified PointCP and PointCPTest

Takes in x and y or rho and theta. Remembers what type was entered.
Stores them as rho and theta.  Recalculates x and y if needed.
Optimization and benchmark

Optimized design 2's pointCP's rotatePoint method (only needs to add
angle since it's already polar).
Benchmarked design 2 with TestDesign.
