SalesCommissionCalculator.java

//Note: Company salespeople are paid $200/ week.
	//Weekly they also receive  9% of gross sales. (0.09 percent).
	//$200 plus 9% of gross sales is what the salespeople earn per week.

//Prompt the salesperson to enter the cost of items sold last week. (Gross sale).
	//Save the value in a double variable.
	//Use indefinite loop to avoid limiting the number of entries.
//Calculate and display that salesperson's total earning for the week.
	//Multiply the gross sales with 0.09. 
	//Add the multiplied result with their weekly $200 earning.
