Fixed when rebuilding non-main() project after main() project: the 'nasty kludge' was looking in ALL the .o files in projectFolder/build/ instead of only those that have a corresponding .cpp/.c/.S file. An even better fix is make sure that object files associated with source files deleted by rsync are removed as well

Open Sound Control
------------------

This example shows an implementation of OSC (Open Sound Control) which was 
developed at UC Berkeley Center for New Music and Audio Technology (CNMAT).

It is designed to be run alongside resources/osc/osc.js

The OSC server port on which to receive is set in `setup()` 
via `oscServer.setup()`. Likewise the OSC client port on which to 
send is set in `oscClient.setup()`.

In `setup()` an OSC message to address `/osc-setup`, it then waits 
1 second for a reply on `/osc-setup-reply`.

in `render()` the code receives OSC messages, parses them, and sends 
back an acknowledgment.
