* licenses/*: Added various license agreements to this folder so 
	that it is clear what code is reusable with ARTS.
	
	* src/lineshapes.cc: Added Algorithm 916 (see code for details) to
	calculate the Faddeeva function. The Faddeeva function offers a
	solution to both the Voigt and Faraday-Voigt lineshapes. The 
	current implementation is very slow, as it calculates the line shapes
	twice even though one calculation is mathematically sufficient. I
	suggest a complex_xsec function returning two vectors in a future
	update instead of returning the real and complex values as separate
	line shapes. The line shapes were tested within the limit of the
	Zeeman model paper and deemed OK.

	* src/Faddeeva.{cc,hh}: Added. The bulk of the new line shape code 
	is in here. These files fall under the MIT/X11 licence. More in the files.
	
	* src/CMakeLists.txt: Faddeeva should be in list in list.

	* src/workspace.cc: Added a phase lineshape variable.
	
	* src/methods.cc: Require another lineshape variable for m_zeeman.cc.
	
	* src/m_zeeman.cc: Split phase from attenuatiion polararization matrices.
	Requires another line shape without caring which type, though for physical
	reason this line shape should be Faraday-Voigt.
	
	* controlfiles/artscomponents/zeeman/*: Changed necessary bits to work since
	a new line shape changes results. Change in reference is on order of 0.02 K.

        * src/abs_species_tags.{h,cc}
	(SpeciesTag::CiaDataset): Added this function (and associated
	private member) to store the index of the dataset to use (inside
	the CIA file), which is also now appended at the end of the CIA
	species tag.
	(SpeciesTag::SpeciesTag): Parse also the new dataset index at the
	end of the CIA tag. It must be present!
	(SpeciesTag::Name): Fixed broken CIA tag name output. Not testet!

        * src/cia.{h,cc}
	(cia_interpolation): Continued to work on this.

        * src/m_cia.cc: Cosmetics.

        * controlfiles/artscomponents/cia/TestCIA.arts: Updated for new
	CIA tag names with dataset index.

            * controlfiles/artscomponents/radiolink/TestRadioOccultation.arts:
            A control file simulating a complete occultation.

            * src/m_ppath.cc (ppathFromRtePos2): The method now operates with a
            target and OK level for the "miss distance". This to allow for
            aimimg at a high acccuracy but not getting an error directly when
            that accuracy can not be achived. To achieve this, variables and
            code added so that the previous ppath can be selected as the
            solution.

            * src/methods.cc: Some further polishing of the text for Append. 

            * src/m_ppath.cc (TangentPointPrint): Extended the output somewhat.

            * controlfiles/artscomponents/radiolink/TestRadioOccultation.arts:
            Missed to do svn add on the file.

            * src/m_ppath.cc (ppathFromRtePos2): Init ip to dummy value of
              -999,
              to avoid compiler warning. And changed defualt for dl_ok to 0.5.
              Seems to cover the worst case for TestRadioOccultation.arts
            (tried
            500 angles).
