function TextBox = editLabels(this,BoxLabel,BoxPool)
%EDITLABELS  Builds group box for editing axes labels.
%
%   TEXTBOX = this.EDITLABELS(GroupBoxLabel,GroupBoxPool) returns the
%   handle TEXTBOX of a group box for editing the title and labels of
%   the axesgroup this.  TEXTBOX is an @editbox instance.
%
%   The group box label is specified by GroupBoxLabel, and EDITLABELS 
%   first scans the group box handle vector GroupBoxPool for a matching 
%   group box (avoids recreating the group box if it already exists, e.g., 
%   in the corresponding property editor tab).
