%PLOT Plot WVTREE object.
%   PLOT(T) plots the WVTREE object T.
%   FIG = PLOT(T) returns the handle of the figure, which
%   contains the tree T.
%   PLOT(T,FIG) plots the tree T in the figure FIG, which
%   already contains a tree.
%
%   PLOT is a graphical tree-management utility. The figure
%   that contains the tree is a GUI tool. It lets you change
%   the Node Label to Depth_Position or Index, and Node Action
%   to Split-Merge or Visualize.
%   The default values are Depth_Position and Visualize.
%
%   You can click the nodes to execute the current Node Action.
%
%   After some split or merge actions you can get the new tree
%   using the handle of the figure, which contains it.
%   You must use the following special syntax:
%       NEWT = PLOT(T,'read',FIG).
%   In fact, the first argument is dummy. Then the most general
%   syntax for this purpose is:
%       NEWT = PLOT(DUMMY,'READ',FIG);
%   where DUMMY is any object parented by an NTREE object.
%
%   DUMMY can be any object constructor name, which returns
%   an object parented by an NTREE object. For example:
%      NEWT = PLOT(ntree,'read',FIG);
%      NEWT = PLOT(dtree,'read',FIG);
