Curve

[geftimov]

Hello,

First to tell you thanks for your great library.
Just yesterday I made similar thing in a project of mine, but yours is almost complete.

As I saw you will like to include directions (down,left,up and right) which is great.
I think the library will be great if there is also a curve expanding/collapsing involved.
I would like to contribute and make an PR with this functionality.

So my question is this:

Do you thing this is good idea to add to the library? (I don't want to waste my time)

Feel free to send a PR with you feature :) We will take a look once the code be ready.
