Parameters:

footprint_xmlrpc	should be an array of arrays, where the top-level array should have 3 or more elements, and the sub-arrays should all have exactly 2 elements (x and y coordinates).
full_param_name	this is the full name of the rosparam from which the footprint_xmlrpc value came. It is used only for reporting errors.
