add InProcessExampleBrowser to make it easy to instantiate the ExampleBrowser in its own thread

example usage:

int main(int argc, char* argv[])
{

btInProcessExampleBrowserInternalData* data = btCreateInProcessExampleBrowser(argc,argv);

while (!(btIsExampleBrowserTerminated(data)))
{
}

btShutDownExampleBrowser(data);

        return 0;
}
