 **Description:  This program allows the user to play the 
 **part of Marty McFly from the classic 80's movie, Back
 **to the Future.  The player 'travels through time' by 
 **accessing pointers which circularly link derived objects. 
 **The derived objects represent an era of time, such as the
 **1950's, 1960's, 1970's, 1980's, and the 1990's.  Once the
 **player collects certain items using a function that
 **utilizes a random seed generator and activates a hidden
 **pointer, then they are able to "travel" back to the 
 **future.
 **linked derived objects
 **Input:       User choices(ints)
 **Output:      Strings based on user choice and pointer
 **accessed

/*************************************************************
 **Function:        travel(Era *&, Player *&)
 **Description:     Once the Era is accessed, it updates 
 **player's current location. 
 **
 **It asks the user if they want to remove anything by letting
 **them display the items, remove one, or ignore and continue.
 **
 **If the correct lyric is guessed, player can collect an item. 
 **
 **Player is given chance to listen to a song.  If the correct
 **song is played, and player has 3 certain items,
 **then the secretPassage pointer is activated and will appear 
 **for the user to choose.  Otherwise, the user is only
 **given the choice of 3 pointers to access--forward, backward,
 **and itself.
 **
 **After player chooses which direction they want to travel
 **to next, the function returns the pointer to that Era. 
 **
 **Parameters:          Era *& (Era to travel to) & Player *&
 **(Player since we are adjusting their private members)
 **Pre-Conditions:      N/A
 **Post-Conditions:     N/A
