Derivatives project

This project take an equation like string as input and return the derivative

INPUT FORMAT:

        ej1: 3x^2+5x+2 -> without  parentheses
        ej2: (3x^2+5x+2)*(2^x) -> with parentheses
        ej3: (3x^2+5x+2)*(x^2+2)

Supported derivative operations: exponential chain rule multiplication summ & diff exponentiation
