; Concepts illustrated:
;   - Illustrates NCL 6.4.0's new default behavior for the mpDataBaseVersion resource
;----------------------------------------------------------------------
; This script generates five plots:
;     - 1st map is completely default behavior, i.e., LowRes w/Geophysical
;       outlines
;     - 2nd map shows that MediumRes is used if mpFillBoundarySet
;       or mpOutlineBoundarySet is anything other than "Geophysical"
;     - 3rd map shows how LowRes can be requested regardless of
;       BoundarySet features.
;     - 4th map shows how MediumRes with just Geophysical features
;       can be requested (useful for highly zoomed in maps).
;     - 5th map shows explicit use of mpDataBaseVersion="Dynamic"
;
