Routine Description:

    BOOL ProcessInfSection
    
    Given a filename and a section this function will process/install all entries
    in an inf section

Arguments:

    lpFilename      - The name of the inf file to process
    lpInfSection    - The name of the inf section to process

Return Value:

    Boolean on whether or not it was able to process the file
