Scope resolution for fields in BST Node

[digambar-t7]

The BTNode in the BinarySearchTreeImplementation has non-private members along with their getter & setter methods.
Getters & Setters are actually required in case of private fields.But in case of non-private members they are not required as we can access them directly.

I suggest either to make the corresponding fields private or remove the getters & setters.Can I raise a pull request for it?

I know I am too late. This type of problem like BinarySearchTreeImplementation is rare and very informative. Please raise a pull request. I have assigned it to you.
