[Paraview] List to select zones in object panel for a custom reader

[burlen]

You don't necessarily need to do a lot of heavy coding.

One simple way to transfer variable length data such as the list of 
selected zone ids from client to server is via a string vector property. 
On the client side you will need a custom panel that handles 
serialization of the list of zones into the string vector property. On 
the server side parse the string during request data phase. A format like:

"nZoneIds Zone1Id Zone2Id ... ZoneNId".

Would do the trick, and would be compatible with PV state.
