/**
* @file
* Hooks provided by the Field group module.
*
* Fieldgroup is a module that will wrap fields and other fieldgroups. Nothing more, nothing less.
* For this there are formatters we can create on forms and view modes.
*
* Some of the elements defined in fieldgroup will be ported to the elements module.
*
* DEVELOPERS NOTES
*
* - Fieldgroup uses a ''#fieldgroups' property to know what fieldgroups are to be pre_rendered and
* rendered by the field_group module. This means we need to be sure our groups are in #fieldgroups.
* #fieldgroups is later merged with the normal #groups that can be used by any other module.
* This is done to be sure fieldgroup is not taking fieldsets from profile2, commerce line items,
* commerce user profiles, ... .
* When trying to merge a programmatically created field wrapper (div, markup, fieldset, ...) into
* groups, you might consider adding it in #field_groups as well if you want the element processed
* by fieldgroup.
