…ynomial_fit, leaving method stubs behind so everything is backwards compatible. The tests still pass without modification, importing from the old places.
… changed name of the general finite_difference function to be finitediff so it doesn't collide with the module name, updated the basic usage notebook to be more in line with the new structure, reran everything

A last case where the former-first-order-which-was-actually-second-order was still being imported as first order, which is now properly first order. I haven't been checking on lineardiff as closely, so this slipped through.

This is just a common pattern to make the functions still importable from the old place, for backwards compatibility.
