'Load a template from the loader.  If a loader is configured this
method ask the loader for the template and returns a :class:`Template`.
If the `parent` parameter is not `None`, :meth:`join_path` is called
to get the real template name before loading.
The `globals` parameter can be used to provide template wide globals.
These variables are available in the context at render time.
If the template does not exist a :exc:`TemplateNotFound` exception is
raised.
.. versionchanged:: 2.4
If `name` is a :class:`Template` object it is returned from the
function unchanged.'
