  * Added new module: Data.Graph.Inductive.PatriciaTree
  
  This is an efficient implementation of Data.Graph.Inductive.Graph.Graph
  using big-endian patricia tree (i.e. Data.IntMap).
  
  This module provides the following specialised functions to gain
  more perfornance, using GHC's RULES pragma:
    * insNode
    * insEdge
    * gmap
    * nmap
    * emap

    A ./Data/Graph/Inductive/PatriciaTree.hs
    M ./fgl.cabal -2 +3
