Enable Matviz to require dax and state we need the tbb backend.
The UI now chooses the accelerated contour algorithm if it was enabled.
Add in the actual accelerated contour algorithm.
Commit more changes to get the accelerated contour found by the client side.
Now cache the sub grid values instead of computing them each time.
Make the computation of the sub grid values parallelized.
LowHigh computation is now actually saved.
Actually contour each sub grid.
Show how we could use VTK instead of dax to the sub grid filtering.
Trying to squeeze some more performance out of dax contour.
Cleanup the Vtk Contour version and parallelize it.
Revert to original contour, and remove the attempt to create xml defs.
Create a new Contour module when acceleration is turned on.
Return the triangles that each sub grid produces.
Merge branch 'master' into dax-contour

Conflicts:

Remove unneeded parameters from SubdividedVolume methods.
Instead of making Contouring a filter make it a streaming representation.

This will allow us to stream to the render the sub sections of the contour
as they get processed, and allow interactive rendering even while we
continue to contour.
Remove the old filter based implementation.
Make a new xml file that describes the new contour representation.
For a first pass make this as a paraview plugin so we can test it.
