Proposing to remove labelangleitemindex, labelitemindex, labelsizeitemindex from the SWIG interface

[Tamas Szekeres]

Folks,

Setting the aforementioned members externally may cause memory
reference errors. These members are handled internally so there's no
use to allow them to set from the SWIG interface.
I'm proposing to hide these items like angleitemindex, sizeitemindex
have already been hidden.

For more details see:

Any objections?
