You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: Empty.m
    path of file: ./repos/BioSigKit/LayoutLib/layout/+uiextras
    
    the code of the file until where you have to start completion: function obj = Empty( varargin )
%uiextras.Empty  Create an empty space
%
%   obj = uiextras.Empty() creates an empty space that can be used to add
%   gaps between elements in layouts.
%
%   obj = uiextras.Empty(param,value,...) also sets one or more property
%   values.
%
%   See the <a href="matlab:doc uiextras.Empty">documentation</a> for more detail and the list of properties.
%
%   Examples:
%   >> f = figure();
%   >> box = uiextras.HBox( 'Parent', f );
%   >> uicontrol( 'Parent', box, 'Background', 'r' )
%   >> uiextras.Empty( 'Parent', box )
%   >> uicontrol( 'Parent', box, 'Background', 'b' )
