* get rid of dependency counter in graph action:
analyze graph directly instead when we need to determine nodes we
need to execute or revert next;
* move graph interpreting to separate class, GraphAnalyzer:
instead of inheriting this code from base graph action we now use
composition;
* get rid of direct dependency of graph action on engine.
Relates to blueprint smart-revert
