/**
   File Name:          15.5.4.11-6.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.
