% rcnn_model = rcnn_load_model(rcnn_model_or_file, use_gpu)
%   Takes an rcnn_model structure and loads the associated Caffe
%   CNN into memory. Since this is nasty global state that is carried
%   around, a randomly generated 'key' (or handle) is returned.
%   Before making calls to caffe it's a good idea to check that
%   rcnn_model.cnn.key is the same as caffe('get_init_key').
