//	A Program represent the jumps that will be part of a competition event. The jumps that will be flown.
//	A Program is a list of jumps, possibly of different disciplines
//
//	The class provides an interface to build the program via strings or figure by figure
//	It also provides an interface to iterate through jumps. Then us the jump iteration to access figures
