Extended features for Dealbook Chartstudio CTL programming

It is a recurring problem with the way CTL programs run that information calculated cannot be carried across to the next iteration of the program. The GetNum and SetNum functions in CTLDLL now provide a way to save and access data from any iteration of the code.
Further, the information can be accessed by any other CTL program – providing a method of global access to variables.

Another challenge to CTL programming is that the code runs at each tick (price change) which will normally happens dozens of times a minute... perhaps hundreds of times an hour. Where CTL programs are working, for example in hourly charts, there could be many wasted or unwanted iterations and re-calculations at each tick.
The EachTime function provides a way to action a CTL iteration after a specific time period.
