* Description : This is the main class for the wine locker application. This class
* 				implements the use of a linked list as well as a queue for the data 
* 				structures. In this class I have methods to add a member to a wait
* 				list if no wine lockers are available, a method to assign a locker to 
* 				a member, a method to remove a member off of the wait list, and other methods
* 				to display information. My project is however unfinished as I did not implement
* 				the insertion sort that I wanted to implement and I also don't have a interface 
* 				included.
*

* Academic Honesty: I attest that this is my original work.
* I have not used unauthorized source code, either modified or
* unmodified. I have not given other fellow student(s) access
* to my program.
