Arrayground – A mobile app for K and BQN

Sadly cannot reach asakura.io pointed by the app.

Obviously resources are related to ngn/k like

- https://razetime.github.io/ngn-k-tutorial/ and (bqn n c) like

- https://mlochbaum.github.io/BQN/

This is very basic but an alternative to those who use j to try apl.
