[Paraview] common calculations module

[Berk Geveci]

Save the following to a .pvs file, change the equation, create your
source, load the .pvs file. Of course, make sure that the names in the
equation match the array names.

set EQUATION {RTData*7}

set kw(vtkTemp1) [$Application GetMainWindow]

set calc [$kw(vtkTemp1) CreatePVSource Calculator]
set calcWidget [$calc GetPVWidget {Equation}]
$calcWidget SetFunctionLabel $EQUATION
