[update of SandwichFeatures]
- more clear naming (primary_seq_distance_cutoff_for_electrostatic_interactions -> min_primary_seq_distance_diff_for_electrostatic_interactions)
- more consistent naming (shortest_dis_between_facing_aro ->
shortest_dis_between_facing_aro_in_sw)
- more consistent naming (shortest_dis_between_sheets_by_aro ->
shortest_dis_between_facing_aro_in_sw)
- may allow to exclude sandwich that has too close distance between facing
aromatic residues
- like
'write_resfile_to_minimize_too_many_core_heading_FWY_on_edge_strands_'
no aro for every 2nd residue for 'write_resfile_to_minimize_too_many_core_heading_FWY_on_core_strands_'
- should not change any integration tests other than (expected) features and features_database_schema (if any)
