Simple JavaCV example in Processing

/**
 * JavaCV in Processing 2.0b5 on MacBook with 64bit
 *
 * OpenCV from MacPorts:
 * - /opt/local/macports/macports.conf needs to have "build_arch" to be set to x86_64
 * - now just do: sudo port install opencv
 *
 * Sketch has the .jar files from this download inside "code" folder (just drag-drop them on sketch window):
 * - http://code.google.com/p/javacv/downloads/detail?name=javacv-0.2-bin.zip
