Add python interface for ELPA

See merge request !8

C interfaces added for:

- elpa_print_settings
- elpa_store_settings
- elpa_load_settings
- elpa_autotune_print_state

Tests are done for:
- elpa_autotune_print_best
- elpa_autotune_print_state
- elpa_print_settings

Also the C interfaces for load/save autotuning are still missing
