TIME functions - reviews and requests

Dear SDWIG,

GeoSPARQL defines both ontology elements (classes and properties) and also
SPARQL extension functions to calculate contains etc.

OWL Time defines ontology elements only.

I have prepared a SPARQL extensions functions library for OWL Time
implemented in Python's rdflib:

   - PyPI package: https://pypi.org/project/timefuncs/
   - GitHub source code: https://github.com/RDFLib/timefuncs

I would be interested in any reviews and also in any requests/suggestions
for functions yet to be implemented. There is no clear fixed set of time
functions that could be implemented for we can surpass functions
corresponding to pairwise object tests of Allen relations by including
functions that might do things like determine what the Allen relationship
is between two objects.

Once the function set is completed, I will re-implement the functions in
Jena too.

Regards,

Nicholas
