  24     ECMA Section:       15.5.4.4 String.prototype.charAt(pos)
  25     Description:        Returns a string containing the character at position
  26                         pos in the string.  If there is no character at that
  27                         string, the result is the empty string.  The result is
  28                         a string value, not a String object.
  29
  30                         When the charAt method is called with one argument,
  31                         pos, the following steps are taken:
  32                         1. Call ToString, with this value as its argument
  33                         2. Call ToInteger pos
  34                         3. Compute the number of characters  in Result(1)
  35                         4. If Result(2) is less than 0 is or not less than
  36                            Result(3), return the empty string
  37                         5. Return a string of length 1 containing one character
  38                            from result (1), the character at position Result(2).
  39
  40                         Note that the charAt function is intentionally generic;
  41                         it does not require that its this value be a String
  42                         object.  Therefore it can be transferred to other kinds
  43                         of objects for use as a method.
  44
  45                         This tests assiging charAt to primitive types..
