Entropy and Gini index experiments

Conclusion:
1. Entropy and Gini index are unique when color and shape are different
2. Entropy and Gini Index are unique (Small Difference) Color remains the same but different shape
3. Entropy and Gini Index are unique (smaller difference) Color and shape are the same Area and size

Shape and Color are the same, however entropy is unique, Gini Index is even more unique
