	B. Define Methods
		- get24hour(time)	>>> passes in time as "10:10 PM ET" and returns 2010 (as int)
		- sortGamesByTime	>>> array sorting function that sorts games by time
		- retrieveGames		>>> the start of the process to display games on the scoreboard
		- displayGames		>>> writes the data into html elements
		- getmySIteams		>>> reads the mySIcom cookie to set MySI games
		- changeTab			>>> changes tabs and content that goes with tab
		- flipSportPage		>>> for tabs where the content has multiple 'pages', this changes from page to page
	C. Trigger MySI games
2. Initialize Scoreboard Object
