Visualization generator missing from tree.h header

[spirosmaggioros]

the simple tree(tree.h header) was lately added and lacks a visualization generator function. You can take the other tree headers as reference to create the generator function(to generate the string) and then to add a simple visualize() function in the class to perform the visualization using the returning string. The graphviz visualization function is ready at vizualization folder, you only need to implement the string generator.

I just reviewed the tree_visualization.h wouldn't the visualization gen for tree.h be also same as that of bst? I just made the tree.h one I can put in a pull request if you don't have it already.

Yes @aveldan, i mention it on my comment. It's nothing different, of course i can do it myself but i want contributors to do it just to get on groove with the repo and contribute more in the future.
