Tests CLUBB's vertical grid generalization by calling advance_clubb_core_api twice -- once in with an ascending grid and once with a descending grid -- and then comparing that the output results are bit-for-bit when run with -O0 optimization.  The test is run for all cases for varying flag sets. In this case, this tests uses flag sets that are taken from CLUBB's host models.

Flag set 1 -- CAM default flag settings
Flag set 2 -- CAM flag settings as found in the clubb_silhs_devel branch of CAM

(The CLUBB default flags are also run as a 3rd test at the end.)
