    File Name:          15.5.4.11-2.js

    ECMA Section:       15.5.4.11 String.prototype.toLowerCase()

    Description:

    Returns a string equal in length to the length of the result of converting

    this object to a string. The result is a string value, not a String object.

    Every character of the result is equal to the corresponding character of the

    string, unless that character has a Unicode 2.0 uppercase equivalent, in which

    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case

    mapping shall be used, which does not depend on implementation or locale.)

    Note that the toLowerCase function is intentionally generic; it does not require

    that its this value be a String object. Therefore it can be transferred to other

    kinds of objects for use as a method.
