Use VisualVM to Measure Performance

[charlesmackenzie]

Purpose
We've been having some performance issues, and VisualVM is a good tool to figure out what's causing problems. I tried this for some time on Mushu without success, but I've found some new leads and this is getting to be a substantial problem.

Project Scope

• Follow the WPIlib tutorial on using VisualVM
• Start tracking down time-wasting functions and memory-wasing objects. Even if we can't easily improve performance, it's good to know what our problems are.

Self-assigning for now, as this requires some Gradle fiddling
