function []=m_map_gcmfaces(fld,varargin);
%object:    gcmfaces front end to m_map
%inputs:    fld is the 2D field to be mapped, or a cell (see below).
%optional:  proj is either the index (integer; 0 by default) of pre-defined
%               projection(s) or parameters to pass to m_proj (cell)
%more so:   other optional paramaters can be provided ONLY AFTER proj,
%           and must take the following form {'name',param1,param2,...}
%           those that are currently active are
%               {'myCaxis',myCaxis} is the color axis ('auto' by default)
%               {'do_m_coast',do_m_coast} adds call to m_coast (1; default) or not (0).
%               {'myCmap',myCmap} is the colormap name ('jet' by default)
%               {'doHold',1} indicates to 'hold on' and superimpose e.g. a contour
%               {'doCbar',1} indicates to include the colorbar (1 by default)
%               {'doLabl',1} indicates to include the axes labels (1 by default)
%               {'doFit',1} indicates to exclude white space (0 by default)
%               {'myShading','flat'} indicates to use flat shading instead of interp
%
%notes:     - for proj==0 (i.e. the default) three panels will be plotted :
%           a mercator projection over mid-latitude, and two polar
%           stereographic projections. The other predefined proj are
%               -1  mollweide or cylindrical projection
%               1   mercator projection only
%               2   arctic stereographic projection only
%               3   antarctic stereographic projection only
%               1.1 and 1.2 are atlantic mercator projections
%           - myTitle is currently not used; it will take the form
%              {'myTitle',myTitle} is the title (none by default)
%           - myCaxis can be specified with more than 2 values, in which
%             case gcmfaces_cb will be used.
%           - if fld is a 2D field we use pcolor to display it
%           - if fld is a cell one can specify the plotting tool.
%             The cell  must then have the form {plotType,FLD,varargin}
%             where plotType is e.g. 'pcolor' or 'contour', FLD is
%             the 2D field to be plotted, and varargin are options
%             to pass over to the contour command.
%           - Hence .e.g. fld={'contour',mygrid.Depth,'r'} will draw
%             red contours, while fld=mygrid.Depth will color shade.
