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.
This is another commit to mostly version the code. There have been a
considerable number of changes and there is functionality that I am
still determining whether it should lie within the manager or the model
class itself. It makes the most sense to possibly add the "Update" or
database manipulation functions on the models themselves. On the other
hand, instead of creating and generating the ID in the model, the
current design is to create the entry in the database first, get the
last insert row ID and create a new and complete model that is returned
back by the function. This allows us to leverage the autoincrement
functionality of the database rather than trying to design a function
and/ or make an additional call to the database.
**NOTE: Code is non-functional due to some classes not having their
errors resolved.
