 gui_ge_open - Load & Display MRI data
 
 Useage: [mri] = gui_ge_open(mri,[command],[parent])
 
 mri is a structure, generated by 'mri_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 mri structure may be returned to the parent when the parent 
 handle is given.
