code: private String getAction(String check, double waitFor) {
          String action = "";
          if (waitFor > 0) {
              action = "Waiting up to " + waitFor + " seconds " + check;
          }

      }
docs: Helper to recordStep, which takes in a check being performed, and determines if a wait is
  occuring or not. If no wait, no action is recorded. If a wait was performed, that wait is
  added to the check, and provided back as the action
  
  @param check   - the check being performed
  @param waitFor - how long was something waited for. Provide 0 if no wait, and therefore no action
  @return String: the wait being performed as the check, or nothing
