18 Convenience function returning a ProvDocument instance.

20 It does a lazy format detection by simply using try/except for all known
21 formats. The deserializers should fail fairly early when data of the
22 wrong type is passed to them thus the try/except is likely cheap. One
23 could of course also do some more advanced format auto-detection but I am
24 not sure that is necessary.
25
26 The downside is that no proper error messages will be produced, use the
27 format parameter to get the actual traceback.
