Fixed #23849 -- Documented the locmem.Loader class.

Some of these other loaders are disabled by default, but you can activate them

by editing your :setting:`TEMPLATE_LOADERS` setting. :setting:`TEMPLATE_LOADERS`

should be a tuple of strings, where each string represents a template loader

should be a tuple of strings or tuples, where each represents a template loader

class. Here are the template loaders that come with Django:

.. currentmodule:: django.template.loaders

    ``django.contrib.admin`` in :setting:`INSTALLED_APPS`, otherwise

    ``django.contrib.admin``’s will be loaded first and yours will be ignored.

    Note that the loader performs an optimization when it is first imported:

    Note that the loader performs an optimization when it first runs:

    it caches a list of which :setting:`INSTALLED_APPS` packages have a

    ``templates`` subdirectory.

    This loader is disabled by default.

``django.template.loaders.locmem.Loader``

.. versionadded:: 1.8

.. class:: locmem.Loader

    Loads templates from a Python dictionary. This is useful for testing.

    This loader takes a dictionary of templates as its first argument::

        TEMPLATE_LOADERS = (

            ('django.template.loaders.locmem.Loader', {

                'index.html': 'content here',

            }),

        )

    This loader is disabled by default.

Django uses the template loaders in order according to the

:setting:`TEMPLATE_LOADERS` setting. It uses each loader until a loader finds a

match.

  its query string as part of the URL (the URL in e.g. ``'djangoproject.com!``

  is ``djangoproject.com``)

* Added a :class:`locmem.Loader <django.template.loaders.locmem.Loader>`

  class that loads Django templates from a Python dictionary.
