Plotting vector fields on quadtree and tree meshes

[thast]

Is this a desirable feature or should it stay limit to the tensormeshes? Or should we offer an automated way to go from fields on a treemesh to a tensormesh for visualization purposes?

I'm sure that this would be useful and is probably possible with the updates Joe has done for plotting on tree meshes.

Plotting models or fields on a tree mesh used to be painfully slow. To circumvent this problem I simply interpolated the tree mesh or fields to a core tensor mesh for plotting. I have not had a chance to play around with plotting on a tree mesh since Joe made some improvements.

@micmitch : @jcapriot 's treemeshes are awesome. But it is not (yet) possible to plot vector fields with the associated Utils. See the caption of the current error message below:

for the interpolation onto tensormesh, that's what we all do for now. But it would be nice to offer a utils that does it in a few lines, instead of having each time to create the mesh, select a subset area, write the interpolations functions in all directions etc.
