     * get( unit, form, cldr )
     *
     * @unit [String] The full type-unit name (eg. duration-second), or the short unit name
     * (eg. second).
     *
     * @form [String] A string describing the form of the unit representation (eg. long,
     * short, narrow).
     *
     * @cldr [Cldr instance].
     *
     * Return the plural map of a unit, eg: "second"
     * { "one": "{0} second",
 *   "other": "{0} seconds" }
     * }
     *
     * Or the Array of plural maps of a compound-unit, eg: "foot-per-second"
     * [ { "one": "{0} foot",
 *     "other": "{0} feet" },
     *   { "one": "{0} second",
 *     "other": "{0} seconds" } ]
     *
     * Uses the precomputed form of a compound-unit if available, eg: "mile-per-hour"
     * { "displayName": "miles per hour",
 *    "unitPattern-count-one": "{0} mile per hour",
 *    "unitPattern-count-other": "{0} miles per hour"
 * },
     *
     * Also supports "/" instead of "-per-", eg. "foot/second", using the precomputed form if
     * available.
     *
     * Or the Array of plural maps of a compound-unit, eg: "foot-per-second"
     * [ { "one": "{0} foot",
 *     "other": "{0} feet" },
     *   { "one": "{0} second",
 *     "other": "{0} seconds" } ]
     *
     * Or undefined in case the unit (or a unit of the compound-unit) doesn't exist.
