====Node class====

The node class deals with the fundamental unit of manipulation in our program, the venerable **Node**.

===Node() constructor===

<code c++>
Node *mynode = new Node;
</code>

^  Function  ^  Parameter(s)  ^  Return value  |
|  Node()  |  none  |  pointer to the newly allocated node  |

Node() is the parameterless constructor that is responsible for creating a new instance of a node.

===Node(int) constructor===
Overloaded constructor that will accept an initial integer value to be assigned to the newly allocated Node's **value** member.

<code c++>
Node *mynode = new Node(4);
</code>

^  Function  ^  Parameter(s)  ^  Return value  |
|  Node(int)  |  integer value to assign as Node's initial value  |  pointer to the newly allocated node  |

===copy()===
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()===
getvalue() will return the value of the current node

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

===setvalue()===
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  |

===delete()===
delete() will delete the node
^  Function  ^  Parameter(s)  ^  Return value  |
| ~Node *delete()| no parameters | no return   |
