+Tests for the main C Macro Collections library. In order to provide a good code coverage, all macros have been expanded and added to `src/*.c`.
+
+* `src` - Since gcov fails to detect code that was expanded by macro, all collections where manually expanded and dumped into their respective source files;
+* `unt` - Unit Tests;
+* `main.c` - Where all tests are compiled together and called by main().
