this.log is undefined.

I'm getting a broken thread from the following line:

• parse-csv/lib/parser.js

  Line 144 in fc492d6

  this.log('Error parsing row ' + String(ii) + '. Wrong number of columns.');

TypeError: this.log is not a function
      at Parser.parse (node_modules/parse-csv/lib/parser.js:144:12)
      at csv (node_modules/parse-csv/index.js:61:25)
      at Function.module.exports.toJSON (node_modules/parse-csv/index.js:94:25)

      at Context.it (tests/validator_index.js:254:38)

I'll submit a PR to add a temporary logger, but please feel free to ignore it and point me in the right direction, if there's a better way.
