function hook_field_purge_instance

Acts when a field instance is being purged.

In field_purge_instance(), after the field instance has been removed from the database, the field storage module has had a chance to run its hook_field_storage_purge_instance(), and the field info cache has been cleared, this hook is invoked on all modules to allow them to respond to the field instance being purged.

Parameters
