Initial commit of freehanded splay tree. Inherits from Binary Search Tree implemenation.
Made BinarySearchNode's right and left children publicly readonly. Corrected for modifying.
Added BSN anon category and overrode readonly property from parent/right/left and root on SplayTree.
Converted _splay() C function to an objective-c function to allow modifying of the root pointer.
Removed balanceTree override as it was unused for SplayTree.
Added SplayTree.[mh] to the project file.
