2D: set a better default loss
Currently when running the notebook on a computer with 4 cores or less the Learner2D
example in learner.ipynb
will stop after the bounds are done.
Adding the area to the loss will ensure there is a minimal area reached.
Personally, I've been using this loss dev * np.sqrt(A) + 0.3 * A
(I added a small prefactor, but that will probably be more difficult to explain) for a while now and it works quite well for me.
