stModuleCompiler eases running of the module compiler.

    The ModuleCompiler class encapsulates running the commandline
    module compiler (checkmodule) and module packager (semodule_package).
    You are likely interested in the create_module_package method.
    
    Several options are controlled via paramaters (only effects the 
    non-refpol builds):
    
     .mls          [boolean] Generate an MLS module (by passed -M to
                   checkmodule). True to generate an MLS module, false
                   otherwise.
                   
     .module       [boolean] Generate a module instead of a base module.
                   True to generate a module, false to generate a base.
                   
     .checkmodule  [string] Fully qualified path to the module compiler.
                   Default is /usr/bin/checkmodule.
                   
     .semodule_package [string] Fully qualified path to the module
                   packager. Defaults to /usr/bin/semodule_package.
     .output       [file object] File object used to write verbose
                   output of the compililation and packaging process.

        sourcename.

        The create_module_package creates a module package saved in a
        file named sourcename (.pp is the standard extension) from a
        source file (.te is the standard extension). The source file
        should contain SELinux policy statements appropriate for a
        base or non-base module (depending on the setting of .module).

        Only file names are accepted, not open file objects or
        descriptors because the command line SELinux tools are used.

        On error a RuntimeError will be raised with a descriptive
        error message.
