Fix bug when interpolating on Chebyshev grid in which the indices were computed with the Chebyshev grids, but the interpolation weights still used the Cartesian grid
`CartesianGridOutput` can output any variable in a Cartesian box (within
the simulation domain) at a prescribed position and extent.
To use it, add a block to the output file like this:
```
<output3>
file_type = cart
variable = hydro_w
dt = 0.1
center_x = 0.0
center_y = 0.0
center_z = 0.0
extent_x = 0.1
extent_y = 0.1
extent_z = 0.2
chebyshev = 1 # 0:uniform grid; 1:Chebyshev-Lobatto grid
```
Note that the extent of the grid is actually half of the extent
variable. This is because we are using the same convention as in
`CartesianGrid`.
This commit also adds `vis/python/cartgrid.py` to read the data produced
by `CartesianGridOutput`
Reset CartesianGrid interpolation indices and weights before interpolation if AMR is enabled

Thanks for catching the bug in AMR. I commented those out for debug earlier and forgot to remove those when committing to the repo |
