/*  QB-262:
Sports tournament organizer: 
Write a program that simulates a sports tournament using a PriorityQueue. The program 
should allow the user to input team names and their win-loss records. The program should 
then prioritize teams based on their win-loss records and add them to the PriorityQueue. 
When it's time for the next match, the program should remove the two highest priority 
teams from the PriorityQueue and display their names.
