"""
This module contains SSA specific config parser:
- has defaults
- adds default values for ones missing in config file
- allows duplicates, the latest value is loaded
- performs value normalization during loading items:
    - to int
    - to float
    - to bool
- 'correlation' is case-insensitive and allowed to be
    on, off, 1, 0, yes, no, true, false
- loads default configuration in case of missing config file
