% GUI_ELEC_OPEN - Load an electrode data file into matlab workspace
%
% Useage: [p] = gui_elec_open(p,[command],[parent])
%
% p is a structure, generated by 'eeg_toolbox_defaults'
% command is either 'init' or 'load'
% parent is a handle to the gui that calls this gui, useful
% for updating the UserData field of the parent from this gui.
% The p structure is returned to the parent when the parent
% handle is given.
