<h2><center>ExpandoTextCtrl</center></h2>

The ExpandoTextCtrl is a multi-line wx.TextCtrl that will
adjust its height on the fly as needed to accomodate the number of
lines needed to display the current content of the control.  It is
assumed that the width of the control will be a fixed value and
that only the height will be adjusted automatically.  If the
control is used in a sizer then the width should be set as part of
the initial or min size of the control.
