// Purpose	: For this assignment, we will need to implement 
//              : a user Interface Class that allows the user to 
//              : enter a number , and to assemble a series of these 
//              : numbers together then display this assemblage on the
//              : user interface . When the user indicates completion 
//              : the Interface Class will send to an instance of the 
//              : Sort Class (the other class which we create) the input 
//              : string the user has entered.
