+ ECMA Section: 15.5.4.9 String.prototype.substring( start )
+ Description:
+
+ 15.5.4.9 String.prototype.substring(start)
+
+ Returns a substring of the result of converting this object to a string,
+ starting from character position start and running to the end of the
+ string. The result is a string value, not a String object.
+
+ If the argument is NaN or negative, it is replaced with zero; if the
+ argument is larger than the length of the string, it is replaced with the
+ length of the string.
+
+ When the substring method is called with one argument start, the following
+ steps are taken:
+
+ 1.Call ToString, giving it the this value as its argument.
+ 2.Call ToInteger(start).
+ 3.Compute the number of characters in Result(1).
+ 4.Compute min(max(Result(2), 0), Result(3)).
+ 5.Return a string whose length is the difference between Result(3) and Result(4),
+ containing characters from Result(1), namely the characters with indices Result(4)
+ through Result(3)1, in ascending order.
