% GUIBUILDACTIVECIRCUIT, by itself, creates a new GUIBUILDACTIVECIRCUIT or raises the existing
% singleton*.
%
% H = GUIBUILDACTIVECIRCUIT returns the handle to a new GUIBUILDACTIVECIRCUIT or the handle to
% the existing singleton*.
%
% GUIBUILDACTIVECIRCUIT('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in GUIBUILDACTIVECIRCUIT.M with the given input arguments.
%
% GUIBUILDACTIVECIRCUIT('Property','Value',...) creates a new GUIBUILDACTIVECIRCUIT or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before GuiBuildActiveCircuit_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to GuiBuildActiveCircuit_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
