Prolog

I've been learning Prolog this month, none of the results so far merit committing to Copperbox. The intention is to code Lint style rules as Prolog rules and use them to check configurations for bad smells.

By configurations I mean structured data that doesn't necessarily have a corresponding AST - program code naturally has an AST representation and a Lint style checker would traverse the AST; but a configuration might have a flat or nearly flat structure, yet still have dependencies / relationships between values. Prolog (or Datalog) seems a natural choice to represent such data and rules - indeed cfengine is a current exemplar.

Copperbox revision 3003.

Work simulating the algorithm style used by Yahama's DX7 synthesizer and others.

The algorithm style is characterized by two parts - a network of operators and the connections between them (on the DX7 the operators were FM phasors) - the algorithm; plus processors that decorated each operator transforming their input and output signals (e.g applying an envelope or filter).

There is a lot that is clunky in my simulation, some can be improved but I need to work out a naming convention for functions with varying input and output arities.
