/* TinyTest: A really really really tiny and simple no-hassle C unit-testing framework.
 *
 * Features:
 *   - No library dependencies. Not even itself. Just a header file.
 *   - Simple ANSI C. Should work with virtually every C or C++ compiler on
 *     virtually any platform.
 *   - Reports assertion failures, including expressions and line numbers.
 *   - Stops test on first failed assertion.
 *   - ANSI color output for maximum visibility.
 *   - Easy to embed in apps for runtime tests (e.g. environment tests).
 *
 * Example Usage:
 *
 *    #include "tinytest.h"
 *    #include "mylib.h"
 *
 *    void test_sheep()
 *    {
 *      ASSERT("Sheep are cool", are_sheep_cool());
 *      ASSERT_EQUALS(4, sheep.legs);
 *    }
 *
 *    void test_cheese()
 *    {
 *      ASSERT("Cheese is tangy", cheese.tanginess > 0);
 *      ASSERT_STRING_EQUALS("Wensleydale", cheese.name);
 *    }
 *
 *    int main()
 *    {
 *      RUN(test_sheep);
 *      RUN(test_cheese);
 *      return TEST_REPORT();
 *    }
 *
 * To run the tests, compile the tests as a binary and run it.
