Class Description

  A PaveVar is a TPaveLabel  specialized to process
  variables and cuts inside a TTreeViewer.
   A TPaveVar object is used by the TTreeViewer to represent
     - a TTree variable
     - a selection expression.
   A TPavevar has the same graphical representation as a TPaveLabel.
   One can only resize the left or right borders (not top/bottom).
   The context menu allows merging (and/or) overlapping TPaveVars.

  This member function is called when a TPaveVar object is clicked.

  If the mouse is clicked inside the box, the box is moved.

  If the mouse is clicked on the 2 edges (L,R), the box is rscaled
  parallel to this edge.
