dimensions with the same names as coordinates seem a bit confusing in general... especially since BOUT++ uses x/y/z both as coordinates (with spacing dx/dy/dz) and often (in the code) as...

Question: what should we name the dimensions and grid-cell-index coordinates in xBOUT? -------------------------------------------------------------------------------------------------------------------------

`psi`, `theta`, `zeta`

`x`, `y`, `z`

`psi_ind`, `theta_ind`, `zeta_ind`

`x_ind`, `y_ind`, `z_ind`

`i`, `j`, `k`

`ix`, `iy`, `iz`

`jx`, `jy`, `jz`

`ix`, `jy`, `kz`
