The csProgressPulse class provides a simple twirling textual cursor built out of the characters '-', '\', '|', and '/'.
This type of functionality is generally used as a sort of pulse beat during indeterminately lengthy computational operations in order to let the user know that progress is being made and that the program is not hanging. By default, the pulse beat is presented to the user by passing CS_MSG_INITIALIZATION to the system print function. This setting may be changed with the SetMessageType() method. To animate the pulse object, call the Step() method each time a unit of work has been completed. At each step a backspace (\b) followed by one of the pulse characters (-, \, |, or /) is printed, except for the very first step, in which case the backspace is omitted. Erase() clears the pulse, if necessary, by printing a backspace, followed by a space (' '), followed by one more backspace. Reset() erases the pulse and then resets the state. Erase() is called automatically by the destructor.
