Intended to use by developers.
As useful and simple as possible.
It is the Workflow framework for a fast and readable code.
With samples and tips.
Now I'm creating examples.
These will show principles of use and work with states.
It takes me the month or more.
Workflow patterns usually get applied in various context, hence the conditions for use shall be explicitly defined and shown in example to prevent from misinterpreting.
Sorry, samples are under construction.
I prepared all cases. it's time to visualize them.
It requires patience of my family. :(
