Fuzzy logic operators & configurable rule inferencing engine

import type { LVarSet, Rule } from "./api.js";
/**
 * Takes an object of input {@link variable}s, an object of output variable,
 * rule array and an object of input values. Evaluates relevant terms of input
 * variables in all matching rules, then combines and defuzzes them using given
 * optional strategy (by default {@link centroidStrategy} w/ its own default
 * options). Returns object of computed output variable values.
 *
 * @remarks
 * The `imply` T-norm (default: {@link tnormMin} is used to transform each
 * rule's output set(s) using each rule's computed/aggregated truth value, as
 * well as each rule's weight. Different T-norms might produce different fuzzy
 * set shapes and different results, even if the defuzz strategy remains
 * constant.
 *
 * The `combine` S-norm (default: {@link snormMax}) is used to combine the
 * relevant output sets of all rules for integration/analysis by the given
 * defuzz `strategy` actually producing the crisp result.
