michael@0:    ECMA Section:       15.5.4.6 String.prototype.indexOf( searchString, pos)
michael@0:    Description:        If the given searchString appears as a substring of the
michael@0:    result of converting this object to a string, at one or
michael@0:    more positions that are at or to the right of the
michael@0:    specified position, then the index of the leftmost such
michael@0:    position is returned; otherwise -1 is returned.  If
michael@0:    positionis undefined or not supplied, 0 is assumed, so
michael@0:    as to search all of the string.
michael@0: 
michael@0:    When the indexOf method is called with two arguments,
michael@0:    searchString and pos, the following steps are taken:
michael@0: 
michael@0:    1. Call ToString, giving it the this value as its
michael@0:    argument.
michael@0:    2. Call ToString(searchString).
michael@0:    3. Call ToInteger(position). (If position is undefined
michael@0:    or not supplied, this step produces the value 0).
michael@0:    4. Compute the number of characters in Result(1).
michael@0:    5. Compute min(max(Result(3), 0), Result(4)).
michael@0:    6. Compute the number of characters in the string that
michael@0:    is Result(2).
michael@0:    7. Compute the smallest possible integer k not smaller
michael@0:    than Result(5) such that k+Result(6) is not greater
michael@0:    than Result(4), and for all nonnegative integers j
michael@0:    less than Result(6), the character at position k+j
michael@0:    of Result(1) is the same as the character at position
michael@0:    j of Result(2); but if there is no such integer k,
michael@0:    then compute the value -1.
michael@0:    8. Return Result(7).
michael@0: 
michael@0:    Note that the indexOf function is intentionally generic;
michael@0:    it does not require that its this value be a String object.
michael@0:    Therefore it can be transferred to other kinds of objects
michael@0:    for use as a method.
