Class Description

HNode

 This is an utility class to build generic trees (not Root trees) like
an HSplitTree or a reconstruction tree.

 A tree is made of arcs (lines joining two nodes) and nodes (the points at
the end or begin of a tree), so a HNode represents one node. This can be
clarified by the following picture:

 So, a HNode supports its subnodes (its sons) and provides functions to
access those subnodes and to add new subnodes.

Allocates a generic node

Allocates a node with name "name" and title "title"

 Deletes the subnodes hanging from this one

 Utility function to build Root trees from trees made from HNode's

 Activates the branches in the Root TTree "tree" that match those defined
in this node

Returns the subnode number i

Returns the first subnode

Returns the last subnode

Adds a new subnode (aSon) and modifies its title to include the title of
the parent node

 Pass the clear signal to each subnode

 Deletes subnodes
