vicon.py now stores positions inside lists, instead of creating new ones.  Removed console messages.  Updated projector to some new parameters, but not sure if they are correct, so left as addition signs.
minor changes
added experiment.py, which defines a state-machine Trial class and a number of repeats to run Experiment class, along with a couple basic state functions.
added isInside(), show(), and hide() functions to trial options, setup experiment.py for importing, and made Mesh.show() and hide() functions return True or False on success/failure.
bugfixes: timer in exp.timeUp() was wrong, to changed to time.time() function.  Now, timing is not tethered to VR framerate.
minor changes to function names
