Updated README.md for the forked repo.
Changed scanEIT.py to scan axial B-field.

Also added plot of polarization rotation to output plot.

Changed output plot format to 'png' for compatibility with existing documents.
Changed couplings and decays:
Moved light polarization to parallel to transverse B-field.
Changed decay factors from excited to ground states so it would be isotropic and add to 1.

Also changed order in SystemParameters struct so it matches argument order.
Added new subdirectory for F=1 to F'=0 transition plots.

Scripts are split into different ranges and accept plot filename as argument.
Different C++ codes solve for different polarizations.

In future, add selection of polarization C++ code as script argument.
Changed script names so auto-complete would differentiate between them easier.
Add updated directory to Cmake build paths.
Changed *-scanEIT.py scripts to show total absorption and polarization rotation.
Added images directory for pushing images to the git wiki.
Attemp to add source terms to KSP solve.
Also fixed Gfactor errors in Zeeman couplings from ADM Package.
Merge pull request #1 from dihm/upstream-hotfixes

Fixes for EIT example from David.
Merge remote-tracking branch 'upstream/master'
Merge pull request #2 from dihm/upstream-hotfixes

Updated scanEIT.py so that it accounts for both circular polarizations.
Merge remote-tracking branch 'upstream/master' with forked master
