search the minimum value in 2-dimesional

[Lee Byerle]

I've found w/ver 1.8 or higher, 'min' of several layers works with lat and
lon varying.  For example, to plot a map of the minimum value in each
z-column over a 2-D area (lat and lon are varying):

ga> d min(var,z=1,z=12)

Alternatively for maximum:

ga> d max(var, z=1,z=12)
