Interfaces for serializing Django objects.
Usage::
from django.core import serializers
json = serializers.serialize("json", some_queryset)
objects = list(serializers.deserialize("json", json))
To add your own serializers, use the SERIALIZATION_MODULES setting::
SERIALIZATION_MODULES = {
"csv" : "path.to.csv.serializer",
"txt" : "path.to.txt.serializer",
}

Stub serializer to hold exception raised during registration
This allows the serializer registration to cache serializers and if there
is an error raised in the process of creating a serializer it will be
raised and passed along to the caller when the serializer is used.

``serializer_module`` should be the fully qualified module name
for the serializer.
If ``serializers`` is provided, the registration will be added
to the provided dictionary.
If ``serializers`` is not provided, the registration will be made
directly into the global register of serializers. Adding serializers
directly is not a thread-safe operation.

Deserialize a stream or a string. Returns an iterator that yields ``(obj,
m2m_relation_dict)``, where ``obj`` is a instantiated -- but *unsaved* --
object, and ``m2m_relation_dict`` is a dictionary of ``{m2m_field_name :
list_of_related_objects}``.

Register built-in and settings-defined serializers. This is done lazily so
that user code has a chance to (e.g.) set up custom settings without
needing to be careful of import order.
