[Paraview] Readers and multiple arrays

[Utkarsh Ayachit]

Here's a snippet of the XML that makes it possible for a domain to
depend on an information property whose values are obtained from  the
server.

      <DoubleVectorProperty name="StartThetaInfo"
        command="GetStartThetaRange"
        information_only="1"
        number_of_elements="2"
        default_values="1 1024">
       <SimpleDoubleInformationHelper />
      </DoubleVectorProperty>

      <DoubleVectorProperty
         name="StartTheta"
         command="SetStartTheta"
         information_property="StartThetaInfo"
         number_of_elements="1"
         animateable="1"
         default_values="0" >
        <DoubleRangeDomain name="range" >
          <RequiredProperties>
              <Property name="StartThetaInfo" function="RangeInfo"/>
          </RequiredProperties>
        </DoubleRangeDomain>
      </DoubleVectorProperty>

The key is to merely refer to the information property as
"RequiredProperties" for the domain.
