c12aaea747 Attempts to get as far as running the MultiMachine. 
In doing so, fixes the long-standing bug that machines that output audio but don't have a listener produce a divide by zero.

ca48497e87 Pulls DynamicMachine out of MachineForTarget and adds MultiConfigurationTarget as a first multiplexer. 2018-01-29 21:49:49 -05:00

d493ea4bca Introduces a multimachine to handle multi-target static analyser outputs. 
Non-functional as of yet.

e025674eb2 The MSX analyser is now smart enough not to be definitive when it's uncertain. 
The cartridge type has also migrated to being a property of the cartridge, prefiguring my intention to discard the static analyser union.

f2519f4fd7 Decided to focus on 'confidence' over 'probability'. 
Besides anything else, it individualises the measure. E.g. two targets can each have a confidence of 0.8 without each giving the wrong answer about probability.

d360b2c62d Standardises the static analyser on std::vector and slightly widens passageway to a machine. 
The SDL target would now be fooled by a hypothetical multi-target, the Mac not yet.

655b971976 Establishes that there is such as a thing as a Konami SCC.
