Add alias *alias* for a debugger command *command*.

Examples:
--------

    alias('ls', 'list')  // 'ls' now is the same as 'list'
    alias('s',  'step))  // 's' is now an alias for 'step".
                         // The above example is done by default.`,
    run: function(alias, cmdName) {
      if (cmdName in intf.commands) {
        const cmd = intf.commands[cmdName];
        intf.aliases[alias] = cmd;
        cmd.aliases.push(alias);
        intf.print(`Alias "${alias}" created for command "${cmdName}"`);
      } else {
        intf.error(`Debugger command '${cmdName}' not found; \
alias ${alias} not set`);
      }
    }
  });
