+This module contains some fake classes and functions to
+calm the rest of the code base. Or provide super minimal
+implementations.
+
+Currently:
+- ObjectId "class": It's a function mostly doing
+  int(init_arg) to convert string primary keys into
+  integer primary keys.
+- InvalidId exception
+- DESCENDING "constant"
