 ## ATTENTION: API change!!!
 
-API change again, Walk() is ready for range-over-func iterators and renamed to All().

 The CBT is implemented as a bitvector, backtracking is just
 a matter of fast cache friendly bitmask operations.

+The child array at each stride level is also popcount compressed.
