+/**
+ *  @brief  Replacement for fopen that concatenates the location of the 
+ *          source tree onto the filename path. 
+ *          It looks in 3 locations:
+ *              - in the current directory, 
+ *              - then it looks in "..", 
+ *              - lastly in the define UNITTEST_SOURCE_DIR which 
+ *                gets defined by CMake.
+ * @param filename 
+ *              Filename relative to base of source directory.
+ * @param prop 
+ *              Second argument to fopen.
