# Labeledwidget
# ----------------------------------------------------------------------
# Implements a labeled widget which contains a label and child site.
# The child site is a frame which can filled with any widget via a 
# derived class or though the use of the childsite method.  This class
# was designed to be a general purpose base class for supporting the 
# combination of label widget and a childsite, where a label may be 
# text, bitmap or image.  The options include the ability to position 
# the label around the childsite widget, modify the font and margin, 
# and control the display of the label.
