		 * Our program prompts the user to enter a list of grades so that they can calculate_
		 * the sum of grades, the averages of each grade, min/max grade, and possible extra credit_
		 * It will then print you off a summary of this information_
		 * In doing this we learned how to create multiple comments with "/*" instead of "//"
		 * how to use an "if" statement in a println in order to add an additional option to the statement
		 * how to take an arbitrary amount of numbers/inputs from a user and calculate results from them
		 * how to use a screen sharing application other than adobe connect so that we can work together_
		 * remotely from our respective homes
		 *
		 *
		 * Variables
		 * Initialize
		 * Request input
		 * Divide the input by grade, counters and sums go up
		 * determine if input is lower/greater than min/max and change min/max accordingly
		 * calculate averages of individual grades and total
		 * calculate sums of individual grades and total
		 * Output
