'''script that does several things (comment out things not needed)
- converts edf files to csv files without any changes in data
- calculates statistics for each subject and its seizures (start, stop, duration)
- selects data and rearanges in in different ways to use later for feature calculation
- plots data for each subject after searangemens
- calculated features for each input file and saves them
