Copy a suitable example file, e.g. "bwg_example.cpp" from subdirectory
"App" to working directory "circurs" (or create a new file).
To compile this file, type "./mo bwg_example". The code will be
complied. For the first time compilation, it will take some time. But once
that is done, for subsequent example files, it will not take that much
An executable "bwg_example" will be created. Run it.
