#validate(record) ⇒ Object

Using multiple validators for passwords sucks because either the user receives a flood of (often redundant) errors, or each validation must become conditional, which can get complex fairly quickly.

This class attempts to perform validations in a specific order of importance and only displays the errors that are relevant.

todo: add tests todo: add more options todo: check for password strength todo: use I18n for errors
