% GRACE_MATLAB_TOOLBOX_SHGRID MATLAB code for GRACE_Matlab_Toolbox_SHGrid.fig
%      GRACE_MATLAB_TOOLBOX_SHGRID, by itself, creates a new GRACE_MATLAB_TOOLBOX_SHGRID or raises the existing
%      singleton*.
%
%      H = GRACE_MATLAB_TOOLBOX_SHGRID returns the handle to a new GRACE_MATLAB_TOOLBOX_SHGRID or the handle to
%      the existing singleton*.
%
%      GRACE_MATLAB_TOOLBOX_SHGRID('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GRACE_MATLAB_TOOLBOX_SHGRID.M with the given input arguments.
%
%      GRACE_MATLAB_TOOLBOX_SHGRID('Property','Value',...) creates a new GRACE_MATLAB_TOOLBOX_SHGRID or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before GRACE_Matlab_Toolbox_SHGrid_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to GRACE_Matlab_Toolbox_SHGrid_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
