Missing bignumber.js

Hi,

I can't compile the codes as the big number.js is missing from debris repository.
I've changed yarn.lock and app/yarn.lock for bignumber.js from

https://github.com/MikeMcl/bignumber.js/commit/b12705646d76f8867861affe0646faaadbd3a55e

and it solved the problem. I have it in my forked repo, and I can make a pull request if needed.

Thanks.

This is solved in the later release..
