Class Description

 Physical tree description.

 Default ctor.

copy constructor

assignment operator

 Constructor with ndaughters.

 Destructor. It deletes the daughters also.

 Cache the global matrix.

 Clear the matrix if not used by other nodes.

 Get the i-th daughter.

 Check if current node has daughters.

 Map this nodepos to a logical node.

 Set this node persistent in cache.
