Scalars.dat moves to results dir

In sequentialEventDriver, scalars.dat is moved to the results dir after the loop
over all events occurs. Also, some edits were made to try to correct an issue with iS
script regulateVnData.py running python3, by changing the #! to read python2.  However,
I am not convinced that this helped, and a better solution may be to force the whole
package to run python2 (this remains to be tested).
