This class focuses on the timing sensitive parts of the protocol. Everything else will be done by Python code. This also establishes that its OK to back a nativeio class with a bitbang implementation when no hardware acceleration exists. When it does, then bitbangio should be used to explicitly bitbang a protocol.
