CLI framework should accept input

[Andrew Nicols]

The CLI framework should allow for developers to ask users for input. For example:

  $sure = $cli->get_input(get_string('areyousure'));

  switch ($sure) {
    case('yes'):
    case('y'):
      // Do something
    default:
      // Don't do it
  }

I believe that Moodle does this (it's used in the upgrade CLI script)

[François Marier (fmarier)]

Actually, I'm not sure we should do this. I mean part of the beauty of the cli installer is that we can use it to fully automate the installation/upgrade of Mahara (e.g. hopefully in the Debian package soon!).

Prompting for input would break this very desirable (in my opinion) feature of your existing solution.
