added cppunit unit testing framework, using cmake, stripped out the original build systems.

added starting point for Bullet unit tests, with one example unit test
Enable the option BUILD_UNIT_TESTS in cmake to build the test. Note that the test doesn't automatically run.

+/*! \brief Manages TestListener.
+ * \ingroup TrackingTestExecution
+ *
+ * A single instance of this class is used when running the test. It is usually
+ * created by the test runner (TestRunner).
+ *
+ * This class shouldn't have to be inherited from. Use a TestListener
+ * or one of its subclasses to be informed of the ongoing tests.
+ * Use a Outputter to receive a test summary once it has finished
+ *
+ * TestResult supplies a template method 'setSynchronizationObject()'
+ * so that subclasses can provide mutual exclusion in the face of multiple
+ * threads.  This can be useful when tests execute in one thread and
+ * they fill a subclass of TestResult which effects change in another 
+ * thread.  To have mutual exclusion, override setSynchronizationObject()
+ * and make sure that you create an instance of ExclusiveZone at the 
+ * beginning of each method.
+ *
+ * \see Test, TestListener, TestResultCollector, Outputter.
