Added a clause to the add shift method that checks the availability and makes sure that the start is later than the end.

Fixed a bug where isManager wasn't properly evaluated, and changed how positions in the employee are separated.

Added comments, and added a method to receive the availability of a new employee. Also fixed a bug in the splitting of some data.

Added the ability for you to check into a shift by passing the shift ID. If you sign in you should know who the employee is and what shifts they work that day. The methods sign you in if you sign in over five minutes early or over five minutes late, in which case you must talk to a manager and they should change your shift to the hours worked.
Also, added a function for calculating the number of hours worked.

Client now supports receiving position messages from the server. Cleaned bug that stopped timeOff requests from updating locally.

Added functionality for availability and requesting time off to the app. The app needs at least one employee in the database to run. Make sure to open the sql file in the repo drop your current table and execute everything from "create database" to the end of the availability table.

Moved to new package for server files. Updated UserThread and DataBaseQuery to work with the both Availability and TimeOff classes.

Employees table now captures the email, phone number, isManager, and wage.
Shift table now captures the availability of the shift. Updated parsing so all employee and shift details are separated by commas.
