 *
 * Originally obtained from "http://cutest.sourceforge.net/" version 1.4.
 *
 * Modified for serf as follows
 *    4) added CuSuiteSetSetupTeardownCallbacks to set a constructor and
 *       destructor per test suite, run for each test.
 *    3) added CuAssertStrnEquals(), CuAssertStrnEquals_Msg() and
 *       CuAssertStrnEquals_LineMsg()
 *    2) removed const from struct CuTest.name
 *    1) added CuStringFree(), CuTestFree(), CuSuiteFree(), and
 *       CuSuiteFreeDeep()
 *    0) reformatted the whitespace (doh!)
