###
  The debug build process - 
    1. delete the build-debug directory
    2. copy all contents from src to build-debug
    3. in the [ '/assets', '/elements', '/', 'vendor-assets' ] directories under 'build-debug': 
      a) compile all *.coffee files and generate source maps
    4. keep watch and redo the tasks as necessary
