====LNode 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  |
|  LNode()  |  none  |  pointer to the newly allocated node   |

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

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

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

^  Function  ^  Parameter(s)  ^  Return value  |
|  LNode()  |    |  pointer to the newly allocated node  |

===copy()===
copy() will duplicate the node's contents, except NULL next and prev
<code c++>
tmp = mynode -> copy();
</code>

^  Function  ^  Parameter(s)  ^  Return value  |
|  notset  |  notset  |  notset  |

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

^  Function  ^  Parameter(s)  ^  Return value  |
|  LNode *getNext()  |  no parameters  |  return value in LNode *pointer  |
<code c++>
location -> setNext(this -> location -> getNext());
</code>

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

^  Function  ^  Parameter(s)  ^  Return value  |
|  LNode *getPrev()  |  no parameters  |  return value in LNode *pointer  |
<code c++>
location -> setPrev(this -> location -> getPrev());
</code>

===setNext()===
setNext() will set the value of the current node

^  Function  ^  Parameter(s)  ^  Return value  |
|  LNode *getNext  |  pointer value to set value of current node  |  none that is know  |
<code c++>
location -> setNext(this -> location -> getNext());
</code>

===setPrev()===
setPrev() will set the value of the current node

^  Function  ^  Parameter(s)  ^  Return value  |
|  LNode *getPrev  |  pointer value to set value of current node  |  none that is know  |
<code c++>
location -> setPrev(this -> location -> getPrev());
</code>
