Made a new Eclipse project. This time, the .project file should be there, allowing for easy creation of the project wherever.
Tentative merge milestone will be when I have an actual fully-working prototype for XY Plots and Pie Charts.
I've found a few problem areas, mostly in the realm of data importing if we only use JFreeChart, but I have ways around that.
The tools that JFreeChart provides are good enough to do a lot of things with, and I want to stick with it for now.

Additionally, I made a .txt file explaining how making a class that displays a chart in a JPanel works, roughly. It's based on a presentation made by a university professor somewhere.
Generally, I'm pretty close to something people could call "significant progress". I should have something else by tomorrow.
