Map identifier: Mp00140

------------------------------------------------------------------------
Map name: logarithmic height to pruning number

------------------------------------------------------------------------
Domain: Dyck paths

------------------------------------------------------------------------
Codomain: Binary trees

------------------------------------------------------------------------
Description: Francon's map from Dyck paths to binary trees.

This bijection sends the logarithmic height of the Dyck path, [[St000920]], to the pruning number of the binary tree, [[St000396]].  The implementation is a literal translation of Knuth's [2].
