docs: //Ask will call UI.Ask with message then wait for UI.Ask to return a response and/or error.
  //It will clean the response by removing any carriage returns and new lines that if finds.
  //Then it will trim the message using the trim variable.
  //Use and empty string to specify you do not want to trim.
  //If a message is not used ("") then it will not prompt user before waiting on a response.
  //AskPrefix is used to prefix message.
