[Paraview] get the sum of a cell or point variable (UNCLASSIFIED)

Hello,

Running in PV client/server mode, is there a calculator function that will
add up all the values of a variable (cell or point variable). 

I can use the programmable filter to write a python loop to iterate through
all the cell/point of the variable and add them up. But, running in a
client/server mode, how would you store that value? Can I just add a single
value (not array) to the data? If so, what vtk data structure shall I use to
store a double variable? vtk.vtkDouble()? Or is there a way to write that
value out to a file. Running it in parallel, how would that be handled?

Thanks
-simon
