some little reshape of the code.
input variables moved into the ED_INPUT_VARS module for better handling.
this required some work on the Hloc reading & manipulation.

renamed some variables in the input file, this will cause some problem at runtime
using old input file:
- lanc_neigen --> lanc_nstates_sector
- lanc_nstates --> lanc_nstates_total
- NL --> Lmats
- Nw --> Lreal
- Nfit --> Lfit
