I'm trying to use the Packet Header Generator block

I assume that an appropriate "formatter object" can
be submitted to this block to instruct it to build an
arbitrary header, but I'm having difficulty finding
any documentation or example of using a formatter object.
All I found points to the packet_header_default::header_formatter
method, which composes a fixed format that is of no use to me.

Any help point me in the right direction?  Am I just missing
it or is there no "generic" header formatter capability?

Hey Ed,

Funny enough, I was just working on this today. I'm adding a similar packet header generator for async (PDU-based) packets. The concept is similar with a default base class that you'd overload for your own purposes for packet formatting. I'll be documenting this behavior more in the blocks themselves, and this should eventually become the basis for another level of our tutorials.

I have it working here in simulation, but I know there's going to be some trouble going over the air. I suspect I'll have something that's is worth sharing and reasonably documented early next week.
