Validation

[jdebecdelievre]

PyFME passed the 2 following validation tests:

• for small perturbations is gives the same answer as what is predicted by the analytical analysis of a linear system (as done in Etin & Reid, Dynamics of Flight)
• for all control inputs and initial conditions I have attempted, it gives the same think as a Matlab Simulink model in which the equations of motion are preimplemented in the "6DOF" block of the Matlab aerospace blockset.
  I did all these tests on a simplified version of the Cessna 172 model (to make it easier to port to Matlab).

I created a "validation folder" containing two notebooks showing these validations steps.
I don't really know how to post the Matlab part of this (it is a simulink block diagram) so for now nothing is posted.

Sorry for my late answer. Thanks for the PR!

This seems pretty impressive and I am really excited about this validation working. I will have a detailed look at it this week and see how to include this validations.
