Better documentation of public members #32
Description
Documentation of the public members of the crate is really sparse. Example in wfc_image makes the implementation a little easier to understand, but I personally don't find it straightforward.
I am currently in process of implementing WFC algorithm in my crate and will compare my implementation to the one derived from this crate. After successfully implementing it over grid type in my crate, I can try to open a PR with some additional documentation - would it be welcome?
