It makes slower the change Target/Source functions
and used only by the In/Out DegMap

Updating tests

Doc and changing heap

Doc bugfix

Using proper return type

Heap not for the dijkstra

It will be used in the minCut algorithm

Really short description of these shortest path algorithms

bugfix (affected x86_64 only)

Named parameter for heap and cross ref
It needs some redesign

Matrixmaps moved to own file

Traits moved to own file
Tag for reference maps
Possibility to handle proper the return type
of the operator[]() const -- value or reference

It will be used in the indegmap, outdegmap types

Added clear function to heaps and concept
