/**
     * These functions are intended to be used with array iteration methods
     * -------------------
     * // Example data:
     * let e1 = { a: 1, b:  2, c: "C" };
     * let e2 = { a: 2, b: 12, c: "D" };
     * let myArray = [ e1, e2 ];
     *
     * // Basic usage, matching a constant
     * myArray.filter(match({a: 1})); // [ e1 ]
     * myArray.filter(match({a: 3})); // [ ]
     *
     * // Matching multiple properties
     * myArray.filter(match({ a: 1, c: "C" }));    // [ e1 ]
     * myArray.filter(match({ a: 1, c: "D" }));    // [ ]
     * myArray.filter(matchAny({ a: 1, c: "D" })); // [ e1, e2 ]
     *
     * // If a function is provided, return the result of the function
     * // called with the corresponding property as its argument.
     * let belowTen = n => n < 10;
     * myArray.filter(match({ a: belowTen, b: belowTen })); // [ e1 ]
     * myArray.filter(matchAny({ a: belowTen, b: belowTen })); // [ e1, e2 ]
