Begun integration of models and managers
The HotelManager class now has been connected to some aspects of the command line interface and is functioning for a few cases such as logging in as a specific guest via email, chaging a guests information and creating a new guest account. This was implemented first over the reservation system to test and implement something on a smaller scale. Furthermore, the reservation depends on an existing guest account since a Guest ID needs to be linked to the reservation that is created. Other changes include redesigning, tweaking/ adjusting, and/ or fixing of other modules that have not yet been implemented or are partially implemented.
