Transliteration of html5 email validator in Firefox

What is it?

From teh codez:

// Function to validate an email address.
// This is a transliteration of the HTML5 email-validation logic
// inside Firefox.  It splits the username and domain portions,
// translates tham into IDN punycode syntax, then does some very
// basic sanity-checking.

How to use it?

var validate = require('micro-email-validator');

validate('user@example.com'); // returns true

validate('foo@foo@foo'); // returns false

validate('例子@example.com'); // returns true, yay

Please note, however, that these rules are more liberal than you might think:

validate('wow_such@unsatisfy'); // returns true

validate('wat@'); // returns true

Have fun!
