//TODO:
//1. move all the HelpCommand format to this class. This class should be moved to other place and reuse by
//   the tool like the check tool
//2. The usage class should allow the user to control the indent level 
//3. For the HelpCommand, you should loop through the subcommand list , use this command usage class to print out.
