/*
 * A test caller provides access to a test case method
 * on a test case class.  Test callers are useful when
 * you want to run an individual test or add it to a
 * suite.
 *
 * Here is an example:
 *
 * class MathTest : public TestCase {
 *         ...
 *     public:
 *         void         setUp ();
 *         void         tearDown ();
 *
 *         void         testAdd ();
 *         void         testSubtract ();
 * };
 *
 * Test *MathTest::suite () {
 *     TestSuite *suite = new TestSuite;
 *
 *     suite->addTest (new TestCaller<MathTest> ("testAdd", testAdd));
 *     return suite;
 * }
 *
 * You can use a TestCaller to bind any test method on a TestCase
 * class, as long as it returns accepts void and returns void.
 *
 * See TestCase
