#
# _BacnetSlavePlug - contains the model (i.e. configuration parameters)
# BacnetSlaveEditorPlug - contains the viewer (and editor, so it includes the 'controller' part of the
# design pattern which in this case is not separated from the viewer)
#
# The _BacnetSlavePlug object is 'permanent', i.e. it exists as long as the beremiz project is open
# The BacnetSlaveEditorPlug object is 'transient', i.e. it exists only while the editor is visible/open
# in the editing panel. It is destoryed whenever
# the user closes the corresponding tab in the
# editing panel, and a new object is created when
# the editor is re-opened.
#
# _BacnetSlavePlug contains: AV_ObjTable, ...
# (these are the objects that actually store the config parameters or 'model'
# and are therefore stored to a file)
#
# _BacnetSlavePlug contains: AV_VarEditor, ...
# (these are the objects that implement a grid table to edit/view the
# corresponding mode parameters)
#
# Logic:
# - The xx_VarEditor classes inherit from wx.grid.Grid
# - The xx_ObjTable classes inherit from wx.grid.PyGridTableBase
# To be more precise, the inheritance tree is actually:
# xx_VarEditor -> ObjectGrid -> CustomGrid -> wx.grid.Grid
# xx_ObjTable -> ObjectTable -> CustomTable -> wx.grid.PyGridTableBase)
#
# Note that wx.grid.Grid is prepared to work with wx.grid.PyGridTableBase as the container of
# data that is displayed and edited in the Grid.
