Refactoring

• a built-in's one positional argument is stated once, and a degree question names the tree it walks (#364) (556af30)
• every rule two passes shared has one home, and a docstring says what a caller needs rather than why (#363) (f24ddd3)
• model: each cross-declaration rule is one method, so a refusal names the rule that raised it (#369) (b25a602)
• piecewise: one block expands itself, holding its names, frame and mask once (#367) (537eadf)
• resolution is one method per node kind, and each operator's dim rule is one function (#368) (c7c2833)
• typesetting: the legend reads what the equations returned rather than state left on the walk (#366) (db96a54)
