Update directory structure and files related to prepare module.
    
    - Previously, automation files related to prepare command were stored
      in the tcar-scripts-prepare directory. This organization makes the
      automation scripts tree non-functional in its pristine state. This
      update moves files related to automation scripts from
      tcar-scripts-prepare directory to Scripts/Modules/Prepare directory.
    
    - Previously, documentation files related to prepare command were
      stored in the tcar-scripts-prepare-doc directory. This update moves
      the documentation files related to prepare command from
      tcar-scripts-prepare-docs directory to Scripts/Documentation/
      directory.
    
    - Previously, localization files related to prepare command were
      stored in the tcar-scripts-prepare/Locales directory. This
      organization makes the automation scripts non-functional in its
      pristine state.  This update moves localization files related to
      prepare command from tcar-scripts-prepare/Locales directory to
      Scripts/Locales directory.
    
    - The COPYING file was removed from this branch to avoid duplicate
      copies of it.
    
    - Update top-comment on function files to coincide with top-comment
      inside tcar function files.
