/**
 * @file
 * CTools' multi-step form wizard tool.
 *
 * This tool enables the creation of multi-step forms that go from one
 * form to another. The forms themselves can allow branching if they
 * like, and there are a number of configurable options to how
 * the wizard operates.
 *
 * The wizard can also be friendly to ajax forms, such as when used
 * with the modal tool.
 *
 * The wizard provides callbacks throughout the process, allowing the
 * owner to control the flow. The general flow of what happens is:
 *
 * Generate a form
 * submit a form
 * based upon button clicked, 'finished', 'next form', 'cancel' or 'return'.
 *
 * Each action has its own callback, so cached objects can be modifed and or
 * turned into real objects. Each callback can make decisions about where to
 * go next if it wishes to override the default flow.
 */

/**
 * Display a multi-step form.
 *
 * Aside from the addition of the $form_info which contains an array of
 * information and configuration so the multi-step wizard can do its thing,
 * this function works a lot like drupal_build_form.
 *
 * Remember that the form builders for this form will receive
 * &$form, &$form_state, NOT just &$form_state and no additional args.
 *
 * @param $form_info
 *   An array of form info. @todo document the array.
 * @param $step
 *   The current form step.
 * @param &$form_state
 *   The form state array; this is a reference so the caller can get back
 *   whatever information the form(s) involved left for it.
