+   File Name:          15.5.4.7-3.js
+   ECMA Section:       15.5.4.7 String.prototype.lastIndexOf( 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 left of the specified position, then the index of the
+   rightmost such position is returned; otherwise -1 is returned. If position
+   is undefined or not supplied, the length of this string value is assumed,
+   so as to search all of the string.
+
+   When the lastIndexOf method is called with two arguments searchString and
+   position, the following steps are taken:
+
+   1.Call ToString, giving it the this value as its argument.
+   2.Call ToString(searchString).
+   3.Call ToNumber(position). (If position is undefined or not supplied, this step produces the value NaN).
+   4.If Result(3) is NaN, use +; otherwise, call ToInteger(Result(3)).
+   5.Compute the number of characters in Result(1).
+   6.Compute min(max(Result(4), 0), Result(5)).
+   7.Compute the number of characters in the string that is Result(2).
+   8.Compute the largest possible integer k not larger than Result(6) such that k+Result(7) is not greater
+   than Result(5), and for all nonnegative integers j less than Result(7), 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.
+
+   1.Return Result(8).
+
+   Note that the lastIndexOf 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.
