This commit versions the inital classes used for reporting. Some of the manager classes have been adjusted so that they can also be used in the reporting system since the queries are very similar. The terminal commands and flow have been improved to further close in on the design spec. Guests who make reservations now abide by the fixed rules determined by the doc. For example Prepaid and 60 day reservations have requirements on how far away a reservation needs to be at minimum. The reservation creation process now takes this into account. The base rate functionality has been hooked up and the queries have been verified to work at least once. The same applies for CheckIn() and CheckOut() functions.
