Made a project with this!

[Goom11]

Hello mcsoto, I made a project using your library. You can see it here:
https://github.com/Goom11/SidewaysMath/
it runs here: https://goom11.github.io/SidewaysMath/

it solves math puzzles like this:

 EGG
+EGG
----
PAGE

where each character represents a digit and the digits must be unique (the solver does not actually check uniqueness)

I'd love it if you have the bandwidth if you could look at my code and see if I utilized your project correctly or if I could have done anything differently. If not, no worries.

Had a lot of fun with this project.
