Implementation of the CIME IRT. (Interim Restart Test)
This test the model's restart capability as well as the short term archiver's interim restart capability
(1) Do a Run of length N with restart at N/2 and DOUT_S_SAVE_INTERIM_RESTART set to TRUE
(2) Archive Run using ST archive tools
(3) Recover first interim restart to the case2 run directory
(4) Start case2 from restart and run to the end of case1
(5) compare results.
