; // Program Description:
; //
; // This module contains the crank function. This function is used to checking
; // the request and preparing the response action for its. The fact that it's
; // crank function means that in one cycle this function can make only one step.
; // That means it can't check and response in this same cycle. It works more
; // like state machine. One step can only repose for actual state and change
; // this state to another. The response for other state occurs in next step.
; //
; //
; //
; // How To Test: See Readme.txt
