//	purpose: Program reads in Ride name and information from text file.
//			 Prompts the user for which method to sort the data and for
//			 ascending or descending order. Rides are stored in Rollercoaster
//			 class. A new object is created for each ride, pointer to object is
//			 stored in array.
