* arts-2-1-833

* controlfiles/CMakeLists.txt:  Activated a Zeeman test if arts-xml-file
is in path.

* controlfiles/artscomponents/zeeman/*:  Adapted the Zeeman test.  Note
that there are differences between the previous HITRAN using test and
this test that uses Agnes catalog.  These differences were at 45 K.

* src/m_zeeman.cc:  Added a simple check to allow the user to set
the magnetic field strength manually.  Useful for model comparisons.

* arts-2-1-834

* controlfiles/CMakeLists.txt:  Added two line mixing tests.

* controlfiles/artscomponents/linemixing/*:  These are the tests.  There
is still no reading routine to get vibrational numbers out of Agnes
catalog, so these tests are only preliminary and will have to be 
extended at a later date when this reading routine is in place.  The 
problem with not reading the vibrational state is that we do not know
inside ARTS which line is supposed to be line matched --- no two lines
are allowed to be matched with the same input.

* controlfiles/artscomponents/zeeman/*:  More strongly linked this test
to arts-xml-data, removing the magnetic field files that this folde used
to contain.

            * src/m_sensor.cc (antenna_responseGaussian)
            (backend_channel_responseGaussian): Just changed to use
            gaussian_response_autogrid.

            (antenna_responseVaryingGaussian): New WSM.

            * src/sensor.cc (gaussian_response): Now this function just
            calculates the gaussian response. That is, a more proper "core"
            function.

            (gaussian_response_autogrid): The old function renamed.This one
            also creates a grid.

* src/linerecord.cc (LineRecord::ReadFromArtscat4Stream):

Parse additional quantum numbers v1, v2, v3 and f. Check that species
is O2 because the format for other species is different.

* arts-2-1-837

* controlfiles/CMakeLists.txt:  Added one slow line mixing test.

* controlfiles/artscomponents/linemixing/*:  There is one more test here
that shows how to set this up for the entire band.  I might add a test
later to show how to do Zeeman for one line but Line Mixing for the
entire band.  The other files are updated because I had forgotten that
artscat4 require all species to be defined.  This error was pointed out
to me by Jana.

* controlfiles/artscomponents/zeeman/*:  The files are updated because I
had forgotten that artscat4 require all species to be defined.
