Arbitrary order field solver documentation may need some clarification

[pordyna]

The current documentation shows figures for the phase velocity error for a very low resolution (3 cells per laser wavelength) that suggest that the new solver requires an order of magnitude shorter timestep, but according to @sbastrakov this is not true for more realistic resolutions. So, maybe we should also include figures for typical resolutions in typical Wakefield and solid-density simulations. @steindev would it be also possible to attach your python scripts in the documentation, like we do it in Models/Field Ionization, so that a user can make an estimate for the optimal time step duration themself?

[sbastrakov]

Perhaps in this section in addition to existing plots for $N_\lambda = 3$ also add a better resolved case.

Note that now PIConGPU outputs phase velocity for the currently used parameters. Of course, this does not mean we shouldn't also provide a script as requested - as PIConGPU output is for informing a user and controlling wrong setups, while a script could help to choose parameters wisely.

cc @steindev just in case

@steindev What is the status of this issue?

[steindev]

On the list.

Is this still planned?
