Advanced expression tree manipulations

I have created a github project for the Taylor series method of ordinary differential equations. It is an addon to odeint and will be one day a part of it.

The Taylor series methods determines the solution of an ODE by its Taylor coefficients. The theory is extremely simple but the difficulty is to determine these coefficients numerically and in an unique way. To do so automatic differentiation is used where the formulas defining the ODE are given as expression trees and are then sequentially evaluated to obtain the n-the derivative or the n-th Taylor coefficient.
