Abstract:  CocoaComponent extension allowing integration of

    a Quartz Composer QCView into Java containers.  Includes

    a testcase in main().

    This sample depends on the Particle System composition found in

    /Developer/Examples/Quartz Composer/Motion Graphics Compositions

    which is installed with the Xcode 2.0 developer examples.
