-    Example:
-        Input:
-            kwargs={"a":1, "b":2},
-            kwarg_list=["c", "d"]

+        kwargs_list: A list or sequence of strings representing all possible keyword parameters to a function.

+        A copy of the original `kwargs` with missing keys from `kwarg_list` defaulted to `None`.

     This is helpful for standardizing the input objects for rendering functions.
     The alternative is lots of awkward `if "some_param" not in kwargs or kwargs["some_param"] == None:` clauses in renderers.
