Node(int)	integer value to assign as Node's initial value	pointer to the newly allocated node

copy() will duplicate the node's contents, except NULL next and prev

Function	Parameter(s)	Return value
Node *copy()	no parameters	pointer to copied node

getvalue() will return the value of the current node

Function	Parameter(s)	Return value
int getvalue()	no parameters	return value in node

setvalue() will set the value of the current node

Function	Parameter(s)	Return value
bool setvalue(int)	integer value to set value of current node	boolean value of success vs failure
