PackedAccessTools contains a few useful definitions given a bitfield variable name and a from..to bits-used range.

PackedAccess uses ctReplace (compile-time search&replace, from scrapple.tools.base), to generate accessors that cut out (or set) a bit of a variable. This is the meat of PackedAccess.

NaturalTypeSize is just the "default" size for a type.

And GroupPackedAccess is just a wrapper template for PackedAccess. All it does is split its parameter tuple into groups that are used to instantiate PackedAccess.

Feel free to ask if you have more specific questions.
