        All instance attributes defined between the top of the __init__ method
        and the _init_ctrls() method call will be available to the Designer
        as valid names bound to properties.

        For an attribute to qualify, it has to have a simple deduceable type;
        Python builtin or wxPython objects.
        If for example the attribute is bound to a variable passed in as a
        parameter, you have to first initialise it to a literal of the same
        type. This value will be used at design time.

        e.g.    def __init__(self, parent, myFrameCaption):
                    self.frameCaption = 'Design time frame caption'
                    self.frameCaption = myFrameCaption
                    self._init_ctrls(parent)

        Now you may add this attribute as a parameter or property value
        in the source by hand.

        In the Inspector property values recognised as special attributes
        will display as bold values and cannot be edited (yet).
