follows `PEP-8 <http://legacy.python.org/dev/peps/pep-0008/>`_:
* Module and package names use lowercase_with_underscores.
* Class names use the CapWords convention.
Regular source code follows these convetions. Spack is a bit
more liberal with its Package names nad Compiler names:
* They can contain '-' as well as '_', but cannot start with '-'.
* They can start with numbers, e.g. "3proxy".
This function converts from the module convention to the class
convention by removing _ and - and converting surrounding
lowercase text to CapWords. If mod_name starts with a number,
the class name returned will be prepended with '_' to make a
valid Python identifier.
