Update `path' functionality:
    
        - Keep parent directory manipulation here.  Remove direct
          manipulation of parallel directories and start calling
          centos-art.sh script functions in order to manipulate parallel
          directory specifically. Documentation actions need to be inside
          documentation functionality, render actions need to be inside
          render functionality, and so on.
    
        - Introduce `--sync', `--quiet', and `--yes' flags in order to
          control syncronization, verbosity and default answer to
          question definitions.
    
        - Fix command-line arguments interpretation. Everything is now
          handled between first and second positional paramenters by means
          of shifting positional parameters when they are found.
    
        - Start using cli_printActionPreamble functionality.
    
        - Start using cli_getRepoParallelDirs functionality.
