function pltmap(latrange,lonrange,latd,lond,mrk,col,label)
% PLTNET  Plots a map of a network of points in decimal degrees
%   with labels.
% Version: 20 Jan 99
% Usage:   pltnet(latrange,lonrange,latd,lond,mrk,col,label)
% Input:   latrange - latitude range of base map [min max] (deg)
%          lonrange - lontidue range of base map [min max] (deg)
%          latd     - latitude of points (deg)
%          lond     - longitude of points (deg)
%          mrk      - symbol marker type for points (string)
%                     [o + * - x . v ^ > < square diamond pentagram
%                      hexagram none]; default='+'
%          col      - symbol marker color for points (string)
%                     [r b g y k] or any ColorSpec; default='k'
%          label    - point labels
