/**
   File Name:          15.5.4.4-4.js
   ECMA Section:       15.5.4.4 String.prototype.charAt(pos)
   Description:        Returns a string containing the character at position
   pos in the string.  If there is no character at that
   string, the result is the empty string.  The result is
   a string value, not a String object.

   When the charAt method is called with one argument,
   pos, the following steps are taken:
   1. Call ToString, with this value as its argument
   2. Call ToInteger pos
   3. Compute the number of characters  in Result(1)
   4. If Result(2) is less than 0 is or not less than
   Result(3), return the empty string
   5. Return a string of length 1 containing one character
   from result (1), the character at position Result(2).

   Note that the charAt 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.

   This tests assiging charAt to primitive types..
