    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..
