Create BinaryNodeTree.cpp

We Still Need:

-getEntry()
-inorderTraverse(void visit(ItemType&))
-moveValuesUpTree(BinaryNode* subTreePtr)
-nonStackInorderTraverse(BinaryNode * subTreePtr)
-postOrder(void visit (ItemType&), BinaryNode * treePtr)
-postOrderTraversal(void visit(ItemType&))
-preOrder(void visit (ItemType&), BinaryNode * treePtr)
-preOrderTraversal(void visit(ItemType&))



There are also a couple methods that need to be modified and cleaned up (like the = operator). But this should give you a framework of what all we have and still need
