quickplots/pyicon_quickplots.py: Moved content of quickplots/qp_link_all.py to quickplots/pyicon_quickplots.py. Now, this needs to be called as function and cannot be called as script anymore.

  * new pyicqp.link_all call
  * improved handling of absolute paths
  * prepare for allowing tave to be given as argument to qp_driver

  * New input strategy: confiugre file is no handed in as argument and
    no longer specified inside the script.
  * Minor restructions.
  * Cleaning up.
  * Try to reduce work load by only loading/calculating necessary data
    when initializing IconData objects.

pyicon/quickplots/qp_driver.py: Bug fix: qp_link_all.py needs to be excuted twice: Once for the time average and once for the simulations.

quickplots/qp_driver.py: Slightly restructuring of web page. Added wind stress curl and Ekman pumping plots.

pyicon/pyicon_IconData.py: Added more variables: 2D land sea mask, earth_rot, rho0, Coriolis parameter.

notebooks/examp_atm_wind_stress_curl.ipynb: Added notebook to derive wind stress curl and Ekman velocity.

  * Added time series ts_tas_gmean and ts_radtop_gmean.
  * Splitted time series of ice_volume into NH and SH and plot min/max
    values instead of mean.
  * Added atm_surface_temp, atm_meridional_wind_stress.
  * Added atm_p_e and atm_10m_wind.
  * Added Psi.
  * Added write_data_range to hplot_base and vplot_base calls.
  * Ajusted some color levels.

quickplots/pyicon_quickplots.py: Allow for min,max plotting in qp_timeseries. Allow for adding constant and multiplitcation with constant.

pyicon/pyicon_plotting.py: Added possible to write data range below plots. Bug fix with respect to contfs and norm.

  * functions and coefficients to derive the curl
  * functions and coefficients for vector reconstructions

quickplots: Added script pyicon_prepare_era.py to calculate ERA time averages once and not each time if quickplots are made.

  * Script can be called with slurm option to prevent wrong matplotlib backend.
  * Restructure: Moved website section discription to the front to avoid
    repetition.
  * Added atmosphere bias plots.
  * More flexible color level of SSS plot (more plots should follow in
    this way)

tools/conda_act_mistral_pyicon_env.sh: And again switching to env pyicon_py38 since it seems to work despite earlier suspission.

pyicon/pyicon_plotting.py shade: Added clev option to shade to allow levels also for pcolormesh plots using norm. Fixed bug which causes problems with contourf plots. All cbticks are labeld if norm is used to also account for uneven distributed color levels.

pyicon/pyicon_tb.py: Fixed bug in level interpolation (calc_vertical_interp_weights and zonal_average_atmosphere). New function nctime_to_datetime64 to calculate numpy.datetime64 objects from netcdf time.

notebooks/examp_plot_timeseries.ipynb: Added new notebook to demonstrate how time series can be plotted.
