Invalid value handling in nTuples
Closes #58 (closed).
The MR makes changes to option files so that invalid value for integer functors are passed by the user when there is no entry in the relations table. For floating point number a nan
is tupled.
To be tested with: Analysis!902 (merged), Rec!2992 (merged)
