Define Field API widget types.

Field API widgets specify how fields are displayed in edit forms. Fields of a given field type may be edited using more than one widget. In this case, the Field UI module allows the site builder to choose which widget to use. Widget types are defined by implementing hook_field_widget_info().

Widgets are Form API elements with additional processing capabilities. Widget hooks are typically called by the Field Attach API during the creation of the field form structure with field_attach_form().
