---Deleted all correlation analysis - will be implemented in python and
linked into gs2crmod soon. Replaced transient amplification calculation
with one that depends on g_exb_start_timestep being set such that a
growing mode is established before flow shear is added. Very simply
max/min calculation consistent with EGH papers and thesis.
Version bump to 0.11.79
