Worked on the all-around framework for decoding sectors back from tracks when closing down a file. Hit the wall that the parser is more observant of CRCs than the WD. No, really. So I guess I have to stop avoiding that whole issue.

Factored the MFM parser out into encodings.

Switched to more conventional runtime polymorphism, also now allowing encoders (shifters as were) to be obtained, as a slightly lower-level interface than vector-of-sectors.

Made a first attempt at Acorn ADFS support plus the start of a suitable analyser.

Added CRC checking to DFS comprehension; fixed a bunch of places where I'd used Objective-C's #import rather than #include.

There's no cache and no CRC checking yet, but this is probably a rough outline of an FM parser.

Parameterised to perform FM and MFM encodings, at least subject to CRCs still being missing.

Started sketching out basic MFM track encoding. Which possibly even means that the shifters don't need to be public?

This possibly correctly encapsultes the lowest level of FM and MFM rules.

Declared support for the Acorn disk files, started hammering out an encoder.
