- New species files
- In findband.f90 ecut parameter has been changed from -30 to -100 to be able to
work with Si core states.
GW fails with LO: one must ro check how excting deals with LO
NLO version 1.0, look for an example to debug
temporal commit
Merge branch 'master' of solsrv.physik.hu-berlin.de:/git/exciting into gw
Still looking for reasons of problems with LO in GW
evecsv is used
Bug with LO seems to be solved
Wrong prefactor (constant) has been revised.
The test case CO2-V (I-42d) seems to be working.
Add an example to calulate NLO in CO2-V structure
A test example and the input decription are added
Merge branch 'master' of solsrv.physik.hu-berlin.de:/git/exciting into nlo
in phonondos/thermodynamics: default of ntemp changed to 200
firs commit of optical branch
Problem with symmetry:
 - exciting's rotation of apw coefficients must be checked!
 - gw code recalculate EVECFV for all points.
 - rotation of Minm does not work correctly

Create new branch GW-no-sym!
fixed bug in libxc for xc=GGA
Still cannot rotate Mi_nm, however |Mi_nm|^2 is correct.
Merge branch 'master' of solsrv.physik.hu-berlin.de:/git/exciting into optical
Terminate exciting with error message when trying to perform xs calculation with spin.
check if wfplot is set to avoid segmentation fault in STM calculation
