Mix-in to provide "magic" growing image lists

### LAZYTREE and LISTCONTROL Methods

'''Get icon indexes for a given node, or None if no associated icon'''

### Local methods...
def AddIcon(self, icon, mask = wx.NullBitmap):

return index
### Customisation point...
def GetIcon( self, node ):
'''Get the actual icon object for a node'''
if hasattr (node,"DIAGRAMICON"):
return node.DIAGRAMICON
