bullet3/UnitTests/cppunit/include/cppunit/TestAssert.h
erwin.coumans a983353f34 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.
