def HandleFile(Job, InputFileName, CorrectOutputFileName, ProblemDict): #FileNameToRun, SystemSuppliedFileList=None):
'''
Process one student's submission on one set of input data.
Parameters:
Job: The named tuple containing, among other things, the files submitted by the student and their contents.
InputFileName: The name (including path if needed) of the ONE file with sample input for this test.
CorrectOutputFileName: The name (including path if needed) of the ONE file with correct output for
the specified input.
FileNameToRun: The name (excluding path) of the ONE file that is to run
to test the student's code. This must be present in Job or
SystemSuppliedFileList.
SystemSuppliedFileList: The (possibly empty or missing) list of other
files (including paths) which are needed to run this problem's code
(class files, driver programs, etc)
Returns:
tuple of strings (Res, Err). Res is a brief description ('Correct',
'Runtime exceeded', etc), and Err is an error message (possibly empty
string).
