> Purpose:
 | This class derives from TGraphDrawer. It draws numbers along the axes at a particular interval. This class is abstract.  
> Instantiation:
 | Always allocate on the heap.  
> Deriving Classes:
 | Deriving classes should override PositionLabel and GetRange. In PositionLabel, they are required to position the label according to a particular x-value. In GetRange, they are required to return the range of the axis they are drawing the labels along.
