Can't require coined

[dionyziz]

After installing coined using npm install coined, I get this error:

dionyziz@erdos ~/workspace/block17 % node
> var coined = require('coined');
Error: Cannot find module 'bcoin/node_modules/bn.js'
    at Function.Module._resolveFilename (module.js:470:15)

I expect this has to do with the fact that the bcoin API has been heavily updated and coined has stayed behind.
