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.

Tweaked disk side density, added call-outs to a WD1770 if the Electron had one (albeit without run_for_cycles yet as I need to figure out the clock rate), added a shell of the basic functions of the WD1770. No implementation yet.

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.

Started on the SSD/DSD support. Realised I had ommitted multiple head support from my disk class. Fixed that.

Switched PCMSegments to std::vector; ensured generated [M]FM tracks are correctly sized, thereby making sure the individual flux windows will be correctly sized.

Adapted pervasively to MSB-first output. Which seems to be correct.

Calling it 'number theory' probably isn't accurate but extracted the CRC stuff and started using it for [M]FM encoding.

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.

Some minor tidying, lots more of the caveman stuff as I try to determine what I'm doing wrong.

Made a first attempt at D64 support. Made an error somewhere but this should be 90% of it.

Reduced possibility of overflow on LCM, improved commenting widely, removed one stale piece of G64 bootstrapping caveman stuff.
