/**

 * @defgroup addressfield_format Address format API

 * @{

 * API for generating address forms and display formats.

 *

 * Addresses forms and display formats are collaboratively generated by one or

 * more format handler plugins. An address with a name and a company, for example,

 * will be generated by three handlers:

 *   - 'address' that will generate the country, locality, street blocks

 *   - 'organisation' that will add the organisation block to the address

 *   - 'name-full' that will add a first name and last name block to the address

 *

 * A format handler is a CTools plugin of type 'addressfield' / 'format'. Each

 * handler is passed the format in turn, and can add to or modify the format.

 *

 * The format itself is a renderable array stub. This stub will be transformed

 * into either a Form API array suitable for use as part of a form or into a

 * renderable array suitable for use with drupal_render(). The following

 * modifications are done:

 *   - when rendering as a form, every element which name (its key in the array)

 *     is a valid addressfield column (see addressfield_field_schema()), will

 *     be transformed into a form element, either using a type explicitly

 *     defined in '#widget_type' or using 'select' if '#options' is set or

 *     'textfield' if it is not. In addition, the '#default_value' of every

 *     field will be populated from the address being edited.

 *   - when rendering as a formatter, every element which name (its key in the array)

 *     is a valid addressfield column (see addressfield_field_schema()), will

 *     be transformed into a renderable element, either using a type explicitly

 *     defined in '#render_type' or else using 'addressfield_container'. When

 *     the type is 'addressfield_container' the element will be rendered as

 *     an HTML element set by '#tag' (default: span).
