% gen_object_display - general function to display an object's content

% format: gen_object_display( obj_struct,indent )

% input: obj_struct - a copy of the object stored inside a structure

% indent - amount of "indent" when printing to the screen
|

|

% output: to the screen

% example: gen_object_display( struct( my_object_handle) );
