Stub `determine_partials`

Issue:

* Stub out `determine_partials` which is a migration of
  `web.webqtl.correlation.correlationFunction.determinePartialsByR` in GN1.

  The function in GN1 has R code from line 188 to line 344. This will need to
  be converted over to Python.

  This function will also need tests.
