Update to allow for reproducibility of older answers for NMME forecasts.
Using default_answer_date of >=20190101 will use the latest code.

@wfcooke I added some suggested changes for this PR. Two are cosmetic, but I think the loop reorder relatively important.

Now that this commit has been revised to use the new runtime parameter REPRODUCE_2018_NMME_ANSWERS instead of a back-dated answer date, and also to address the more stylistic changes, it now looks acceptable to me. I am approving it pending successful pipeline testing.

Uses DEFAULT_ANSWER_DATE <20190101 to reproduce forecast results from older executable.
Will change logfiles due to new parameter (REPRODUCE_2018_NMME_ANSWERS) being added.
