Example - obtain datafile information for all datafiles in a given ICAT investigation.

# Assumes you have logged in and stored the session information that is
# returned from CatalogLogin() inside the session variable.
datafiles = CatalogGetDataFiles(InvestigationId = '1390028', Session = session.getPropertyValue("Session"))

# Verify that we have any datafiles in the returned workspace.
print("The number of datafiles in this investigation is: {}".format(len(datafiles)))
