/**

 * Override the default Views data for a Field API field.

 *

 * The field module's implementation of hook_views_data() invokes this for each

 * field storage, in the module that defines the field type. It is not invoked

 * in other modules.

 * When collecting the views data, views_views_data() invokes this hook for each

 * field storage definition, on the module that provides the field storage

 * definition. If the return value is empty, the result of

 * views_field_default_views_data() is used instead. Then the result is altered

 * by invoking hook_field_views_data_alter() on all modules.

 *

 * If no hook implementation exists, hook_views_data() falls back to

 * views_field_default_views_data().
