class RooGraphNode: public TObject

RooGraphNode:                                                              

The purpose of this class is to create nodes, based from the TEllipse class
that have a position, name, and energy that is drawn on the graph with the 
node.  The energy is determined by the topology of the system of nodes the 
node is drawn with and the edges it is attached with and is calculated from
a system of strings that attach all the nodes in the system.

void SetText(TString text)
Changes the name and attached string of the node to given string
void GetNumber(double number)
draws the given number value to the screen at the node location.
This is a number or value associated with the node.
void GetValue(double number, TList* padlist, TList* edges)
TEllipse * GetEllipse(TList* padlist)
Returns the ellipse that was created by drawing this ellipse to the current
canvas by finding it from the list of canvas objects.
