[Paraview] Problem with plugin reader and GUI selection

[Utkarsh Ayachit]

Look at ParaViewSource/Servers/ServerManager/Resources/readers.xml

Almost all readers have properties like CellArrayStatus/CellArrayInfo
or PointArrayStatus/PointArrayInfo. You want to define your reader xml
similarly. Note that it expects your reader to have API as

* int GetNumberOf<Attribute>Arrays
* const char* Get<Attribute>ArrayName (int index)
* int Get<Attribute>ArrayStatus(const char* arrayname)

Where <Attribute> is replaced by the value for the XML item
"attribute_name" specified on  the ArraySelectionInformationHelper
element.

Hope that helps.
