Splitting logic of reclimer and "rope" which deletion list is based on.
Big changes.
1) Now, dynamically resized deletion list is based on rope
2) rope - container provides doubling each time expanding needed;
   it is based on "hierarchical map" structure provides fast
   search through sparse arrays;
3) search with "hierarchical map" is based on "bob-up/sink"
   iterative algorithm
4) Reclamation algorithm is fully implemented.
Some formulas for brainteasing tasks.
