Describe the update

This is the companion update to issue #228 by @nicholasbalasus. This fixes incorrect longitude definitions XMIN and XMAX in the HEMCO_sa_Grid.025x03125.rc and HEMCO_sa_Grid.05x0625.rc. Please see issue #228 for discussion.

Also added explanatory comments to make it clear that the XMIN, XMAX, YMIN, YMAX are edges of the grid.

# Emission grid specifications:
XMIN: -180.15625   # Westernmost longitude edge
XMAX:  179.84375   # Easternmost longitude edge
YMIN: -90.0        # Southernmost latitude edge
YMAX:  90.0        # Northernmost latititude edge
NX: 1152           # Number of longitudes in grid
NY: 721            # Number of latitudes in grid
NZ: 47             # Number of levels in grid

Expected changes

This only affects HEMCO standalone simulations using 0.25x0.3125 or 0.5x0.625 grids. For these simulations, the horizontal grid will now be correct.
