I didn't see this anywhere in the documentation, but is there a way to have nested config variables in the config schema definition? For example:

var config = require('convict')({
  loggly: {
    token: {
      doc: '',
      format: String,
      env: 'LOGGLY_TOKEN'
    },
    subdomain: {
      doc: '',
      format: String,
      env: 'LOGGLY_SUBDOMAIN'
    }
  }
});

edit: Or is there another way to go about this completely? My only requirement would be to not store the information in a file. I know I can do nested config there, but I want the schema functionality to get the config variables from environment variables.
