Modified: weaver.py

Extended the Basic "3-panel" Layout using Horizontal and Vertical Group
  Widgetry... otherwise appears more code-complete.

Only requires "self.Bind()" method calls to connect "self.gadget"
  to "self.function" calling convention.

Only 1 bug at this time,  the "ShellView" Gadget needs to be read-only,
  and multi-line text display... not editable as now... Which gadget?
