Warnings

If citekeys are missing or if a footnote link points to a footnote that does not exist, a warning of the type CiteprocWarning is created and appended to a list. To get all warnings after the conversion process, call get_warnings() on the extension instance. Warnings can be converted to str for logging or output. Warnings can also be raised as Exceptions of the type CiteprocStrictException with raise_() called on a warning object. If strict=True is set in the extensions constructor, every warning is raised as an exception.
