MST2.2
version: 1.0: April 2017 by Xianglin Liu
==================================================================
Description:
   This new version includes implementation of the sine and cosine
   formalism of the relativistic KKR method 
   (In this version the magnetic part and CPA part haven't been fully 
   implemented)
===================================================================
The following files are changed to enable the Dirac solver:
   src/Makefile
   src/AdaptIntegrationModule.F90
   src/CrystalMatrixModule.F90
   src/GFMethodModule.F90
   src/PhysParamModule.F90
   src/convertGijToRel.F90 !NOTE that the previous one by Yang has been replaced
-------------------------------------------------------------------
The following files are added to enable Dirac solver:
   RelSSSolverModule.F90
   RelMSSolverModule.F90
-------------------------------------------------------------------
The following files are MT-relativistic KKR based on Markus Eisenbach's code.
It is not used in the current version.
   src/RelScattererModule.F90
   src/RelGreenFunctionModule.F90
   src/DiracSolverModule
