michael@0:    ECMA Section:       15.5.4.11 String.prototype.toLowerCase()
michael@0:    Description:
michael@0: 
michael@0:    Returns a string equal in length to the length of the result of converting
michael@0:    this object to a string. The result is a string value, not a String object.
michael@0: 
michael@0:    Every character of the result is equal to the corresponding character of the
michael@0:    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
michael@0:    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
michael@0:    mapping shall be used, which does not depend on implementation or locale.)
michael@0: 
michael@0:    Note that the toLowerCase function is intentionally generic; it does not require
michael@0:    that its this value be a String object. Therefore it can be transferred to other
michael@0:    kinds of objects for use as a method.
