Tuned visuals of particles, generation rate. Added 'Flags' timeline to trigger events that change the look of the presentation at certain times. Cleaned up the code a bit (removed duplicate constants, some old comments, added deletion of allocated memory in exit() function, destructor).
Also added the references to ofxMSAFluid and ofxMSACore back in, for easy access and code browsing, since this is educational. Not actually used in the project.
