 *  Description: Shows how to draw high-resolution coastlines using the
 *  RANGS (Regionally Accessible Nested Global Shorelines), developed
 *  by Rainer Feistel from Wessel and Smith's GSHHS (Global
 *  Self-consistent Hierarchical High-resolution Shoreline) database.
 *  To access the RANGS/GSHHS database, you must first download it from
 *  Rainer Feistel's web site at
 *  http://www.io-warnemuende.de/homepages/rfeistel/index.html.  Right
 *  before the section entitled "Some WWW Links", you should see a
 *  little table with ten *.zip files to download:
 *
 *    rangs(0).zip         gshhs(0).zip
 *    rangs(1).zip         gshhs(1).zip
 *    rangs(2).zip         gshhs(2).zip
 *    rangs(3).zip         gshhs(3).zip
 *    rangs(4).zip         gshhs(4).zip
 *
 *  You must download all ten of these files, unzip them, and either
 *  put them in the default directory
 *  "$NCARG_ROOT/lib/ncarg/database/rangs", or put them somewhere else
 *  and set the environment variable NCARG_RANGS to this directory. The
 *  files take up about 140 megabytes, unzipped. Once you have the
 *  files in the appropriate location, then set the mpDataBaseVersion
 *  resource to "RANGS_GSHHS" to create maps using this database. You
 *  should not use this database to plot maximal area plots, because 1)
 *  you will get horizontal lines through your plot, and 2) it takes a
 *   long time.
