- NOT working yet, crashes without exception!  Any ideas?
- pyGridTableBase -> GridTableBase
- GetNumberRows and GetNumberCols have to be overridden, so just uncommented existing
- reset all to 'tab' indentation
- hyperlink is now in wx.lib.agw
- runs but using "Load Image" image doesn't show, need to revisit
- EmptyBitmap -> Bitmap
- Add signature different for spacer, but there must be a nicer way to fix this
