"""
Implementation of the CIME pause/resume test: Tests having driver
'pause' (write cpl restart file) and 'resume' (read cpl restart file)
possibly changing the restart file. Compared to non-pause/resume run.
Test can also be run with other component combinations.
Test requires DESP component to function correctly.
