Fuel moisture model pull request final changes 2020

Final changes:

• update the PR commit message, there should be 15 files modified

• km_opt=5 fix is in the develop branch, merge

• registry package using fmoist_run variable

• perhaps remove fmoist_freq and just leave fmoist_dt

• In module_fr_fire_driver.F, there is a comment about “time – assume dt does not change”. Is that true or does the FFM work also with time varying dt?

• does the FFM work with restart?

• The call to fire_driver_em() has now fire_ifun_end = 2, where it used to be 3. According to the code comments in module_fr_fire_driver.F, fire_ifun_end = 3 has to do with initialization of time step. Is that skipped now or embedded within fire_ifun_end = 2?

• How are the fuel classes initialized for a real case? It seems that the FM values are prescribed from the solution of the fuel moisture model? Could you document/explain that?
