RunExEngineTestITk.py can now be asked to process the output from CreateMisalignmentITk.py
-RunExEngineTestITk.py should now accept an optional argument called MisalignMode, this argument will indicate that we want to use the misalignment files produced by CreateMisalignmentITk.py as input.
-Fix to CreateMisalignmentITk.py solving a problem with the MisalignMode being registered as a string instead of an integer.
