-- Finds the citeref in an expanded CS1/2 template. Takes a test_parameters
-- table and a specific template invoke's args. The test_parameters table has
-- the following fields:
-- * base_args, a table representing the template args common to the test case.
-- * pattern, a string to find in the expanded template
-- * frame, usually from mw.getCurrentFrame()
-- * template, a string which is the name of the template to test.
-- targs is a table of the template arguments unique to the specific assertion.
