this needs to be reworked. there are three essential parts
(0. if not java, then use another 'engine'.. i.e. python)
1. do the p5 language preprocessing
-> this creates a working .java file in a specific location
better yet, just takes a chunk of java code and returns a new/better string
editor can take care of saving this to a file location
2. compile the code from that location
-| catching errors along the way
-| currently done with kjc, but would be nice to use jikes
-> placing it in a ready classpath, or .. ?
3. run the code
needs to communicate location for window
and maybe setup presentation space as well
-> currently done internally
-> would be nice to use external (at least on non-os9)
afterwards, some of these steps need a cleanup function
