% M_Map - mapping toolbox (Author: rich@eos.ubc.ca)
% Version 1.4d 1 Oct 2008
%
% You have collected your data, loaded it into Matlab, analyzed 
% everything to death, and now you want to make a simple map showing 
% how it relates to the world. 
%
% But you can't. 
%
% Instead you have to figure out how to save all your data, and 
% then read it into a mapping program, and then spend all that extra 
% time figuring out why the mapping program doesn't give you what
% you expected it would...
%
% No more! 
%
%                            Announcing M_Map v1.4! 
%
% M_Map is a set of mapping tools written for Matlab v5. These include: 
%
%    1. Routines to project data in 18 different spherical 
%       projections (and determine inverse mappings) 
%    2. A grid generation routine to make nice axes with 
%       limits either in long/lat terms or in planar
%       X/Y terms. 
%    3. A coastline database (with 1/4 degree resolution) 
%    4. A global elevation database (1 degree resolution) 
%    5. Hooks into freely available high-resolution coastlines and
%       bathymetry/topography.
%
% M_Map v1.4 is available via the web at 
%
