---------------------
Config file structure has changed.
Introduced table configuration file, relevant for CSV files processing.
Now more columns in a CSV can be processed, and configuration, more articulated, can be decided there.
The tool goes on also if data are partially available.
Environment variable SA_DEBUG can be set to "on" for deep inspection.
CSV header check improved.
Added a demo.
Boot error handling improved.
General error handling improved.
Tool completely agnostic as to whether x-axis is a time or not.
CSV loading bug fixed.
