// Constructor
// - Initializes customer fName and lName and id from parameters. Creates a new
//   List object for the 'history' pointer to point to. History is a pointer to
//   a list object which will store a Customer's transaction history.

// appendHistory
// - Will append a Trasaction object into a List for 'this' Customer. Actual
//   insertion is handled by 'insert' function of List. If insertion is
//   successful, true will be returned and function will exit. If false is
//   returned, will display a message stating Transaction object was not
//   inserted.
