Checks that the tumbler library in use is compatible with the given version. Generally you would pass in the constants TUMBLER_MAJOR_VERSION, TUMBLER_MINOR_VERSION and TUMBLER_MICRO_VERSION as the three arguments to this function; that produces a check that the library in use is compatible with the version of tumbler the application was compiled against.
