[nclpy-group] Thoughts on changing NCL's default map database to "MediumRes"

[Carl Schreck]

Hi Alan,

As for the defaults, I use a function like these two:

https://k3.cicsnc.org/carl/carl-ncl-library/blob/master/cjs_graphics/cjs_shade_defaults.ncl
https://k3.cicsnc.org/carl/carl-ncl-library/blob/master/cjs_graphics/cjs_draw_shaded_map.ncl

The first one sets things that I always do in shading, the second calls
that first one and draws it on a map. Not sure why I never thought of
setting the map limits automatically in there.
