Document Generic Packet Parsing #190
Description
Summary
In 6.0.0 we added support for generic packet parsing by allowing users to specify their own packet bytes generator for parsing. We included a default ccsds_generator and a simple fixed length generator in the package.
We need to document how to do this in the user documentation.
Suggested Changes
This documentation should include a brief discussion of how XTCE is not limited to CCSDS packets and can support packet definitions for packets that lack a CCSDS header. The only real requirement is that the user can provide a generator that splits a binary stream into individual packets worth of bytes (e.g. by assuming a fixed length or by using a custom field in the packet to determine its length).
Also include an example of how to provide a custom generator for a non-CCSDS packet type. If it's short, this example could go inline but it might be better to put it in the examples directory. Make sure to include a reference to this example in the examples section of the user docs.
