Question about where we can put libraries.  I'm running a class on processing at my school, and we have it installed on the machines in the lab.  Unfortunately, this means we don't have write access to the libraries directory, so we can't add new libraries to our installations.  

Is there another location we could use, perhaps an easy way to change the classpath?  Is there a way to add in libraries on a sketch-by-sketch basis?  Any suggestions would be very much appreciated.
