Added features of system user and unique entry ids
Includes:
Getting system user name form configuration data and implement its recoding in the creation of events and commitments
Events and commitments have absoluteID feature that records date and dime of creation as a unique data for Id
Commands for checking events and commitments for: belong to current user, belong to given user, contains given absoluteId, contains given Event of Commitment’s absoluteId
All features were tested, but due to requiring the user structure of the system, it was done through implementing the functions inside a GUI event.  Tests are recorded separately for if needed again
