I used it on a large tree structure. Here the result of any element is 
dependent on itself and the elements below it. Though the elements below it 
are not exactly the same. They have the exact same structure, inputs and 
results for the formula, but the calculation is different. The most simple 
way to compute the graph is to use recursion on it.
