function editBoxEnable(handles,data,status,varargin)
% function editBoxEnable(handles,data,status,varargin)
% Purpose: Modify the edit boxes' 'Enable' status
% handles: handles of all GUI tools used
% status: 'On' or 'Off'
% varargin specifies which edit boxes to change the status.
% For example, [1:6 22 23] (motion panel only) or [1:20 22 23]
% to change the status for all defined boxes. The order is not
% relevant. The fact that the not all edit boxes are defined is
% the reason behind writing this function.
