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