// Extracted from signUp.js to validate any form using some basic conventions.
// If the form has an error, it will be set to class formErr, then back to formOkay if no errors are found.

// Checks the validity of every item in the rules array.
// Each item will itself be an array with the following key mappings (0: object id, 1: regex to match, 2: string to display for errors).
//
// Returns true on success, false on failed validation.
//
// TODO: Make this form focus() the first field with an error in it.
