It was not auto-generated, if you mean this. I created it with an editor.

Is it a 'noblock', or is it something else
The signal is a C++ class, derived from digital::packet_header_default, 
which is not a GNU Radio block:

I'm not sure what you mean here, but the files for the signal field were 
not created with gr_modtool... The split between main class and *_impl 
is more about swig bindings and makes also sense for non-blocks.
