Documentation for Burger equation discovery #3

Description

@georgemilosh

I ran python3 ./main.py with setting.txt set to Discovery and then to Extraction.

But the output seems strange:

The #1 most likely PDE gives a residual of 0.0071 (3953.11% better than the next sparsest PDE).
D_t U = -1.986161  + -0.159162(U) + -0.120095(D_x U) + -0.473282(D_x^2 U) + -0.111699(U)(U) + -0.825335(U)(D_x^2 U) + -0.020040(U)(U)(U) + -0.253458(U)(U)(D_x^2 U)

Do you need some special set of hyperparameters to recover the Burger equation appropriately?

On this note, it would benefit both the paper and the repo to have a kind of jupyter notebook tutorial rather than putting everything in README or settings.
