/**
   File Name:          15.5.2.js
   ECMA Section:       15.5.2 The String Constructor
   15.5.2.1 new String(value)
   15.5.2.2 new String()

   Description:	When String is called as part of a new expression, it
   is a constructor; it initializes the newly constructed
   object.

   - The prototype property of the newly constructed
   object is set to the original String prototype object,
   the one that is the intial value of String.prototype
   - The internal [[Class]] property of the object is "String"
   - The value of the object is ToString(value).
   - If no value is specified, its value is the empty string.
