background_removal_gui_2.m

% Thing I'd like to add: ability to lock all the figures from a point, so
% that when you zoom in or scan one fig, you zoom in and scan all the figs
% for that point. Probably have to keep track of each figure, and also add
% listeners to all them or something.

function varargout = background_removal_gui_2(varargin)
% BACKGROUND_REMOVAL_GUI_2 MATLAB code for background_removal_gui_2.fig
%      BACKGROUND_REMOVAL_GUI_2, by itself, creates a new BACKGROUND_REMOVAL_GUI_2 or raises the existing
%      singleton*.
%
%      H = BACKGROUND_REMOVAL_GUI_2 returns the handle to a new BACKGROUND_REMOVAL_GUI_2 or the handle to
%      the existing singleton*.
%
%      BACKGROUND_REMOVAL_GUI_2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in BACKGROUND_REMOVAL_GUI_2.M with the given input arguments.
%
%      BACKGROUND_REMOVAL_GUI_2('Property','value',...) creates a new BACKGROUND_REMOVAL_GUI_2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before background_removal_gui_2_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to background_removal_gui_2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
