Introduced an NMI/wait interrupt timing test, and adjusted the Z80 to conform to information posted by Wilf Rigter.

Renamed MachineCycle to PartialMachineCycle given that it mostly no longer intends to describe an entire machine cycle.

Sought to simplify the way partial machine cycles are communicated, for ease of machine implementation. Also implemented the wait line.

Started trying to wade back to passing tests. Working on the new timing tests first, and focussing on getting the Objective-C test machine to compile bus operations into machine cycles, which means indicating phase to all-RAM delegates.

Implemented a rudimentary way to test that instructions take as long as the FUSE tests think they should. Hence discovered that the (HL)-accessing BIT, RES and SET weren't. Corrected.

Plumbed through to allow interrupt tests, wrote an NMI test, corrected the error revealed.

Made an attempt, flawed so far, to find a neat way for processor subclasses to offer bus management as an inline function.

Switched to supplying the bus operation by reference, go guarantee that it isn't null.

Added a memory access delegate to the Z80 all-ram processor, to allow access patterns to be captured.

Factored out the stuff that both all-RAM processors would share, rather than duplicating it.

Continued edging towards getting the absolute basics of a testable Z80, for test-driven development. Corrected old-fashioned instance naming issues with the corresponding 6502 class and removed an unnecessary source file while at it.
