Update the data screening (sorting out of errorneous profiles) for MLS version 4 data based on the MLS documentation. Some cases were not considered so far (in particular the HNO3-190 swath)

Fix crash in newer Matlab versions when trying to access the points variable in certain ways (that breaks pretty many scripts). Caused by a nonbackwards-compatible and not well-documented change in how Matlab handles custom indexing into objects. Great...

Fix issue of matlab2011b crashing when trying to start parallel slaves due to an operating system issue related to opening graphics

A quick update of the chemistry scheme to the JPL19 catalogue. Note that now all functions with jpl16 in name actually use jpl19 data. Was too lazy to change all of these names (which would also break many start scripts)

Some changes to the tracer option CRISTEN_TRACER that proved to be helpful. Some other changes in this commit seem only to be changes in spaces

Discovered that get_data_path has never been uploaded to the repository, although it is needed to run Atlas... Things like this happen if you are the (almost) only user

Large update to make all parts of Atlas work with ERA5 data. In addition, took the opportunity to overhaul the parallel trajectory functions to catch up with the changes and improvements in the main trajectory function.

... and update geopotential height calculation to take into account the change in treatment of orography

Changes to loading orography. Load only once for Interim etc. Add missing function to load orograraphy for ERA5

Fix bug that minimum temperatures and crossing of 80 percent psurf were not recorded if happening at the first trajectory time step

Add possibility to use ERA5 for convection and heating rates, change time step for ERA5, update some default pathes, streamline code for loading heating rates and convection variables a bit

Change time steps loaded from ERA5 files, insert a dot in definition of theta_factor to indicate elemtn-wise division

Added checks in the loading routines for ECMWF data if latitudes start at -90 degrees, longitudes start at 0 degrees and levels and at model level 1
