+   File Name:          15.5.4.8-3.js
+   ECMA Section:       15.5.4.8 String.prototype.split( separator )
+   Description:
+
+   Returns an Array object into which substrings of the result of converting
+   this object to a string have been stored. The substrings are determined by
+   searching from left to right for occurrences of the given separator; these
+   occurrences are not part of any substring in the returned array, but serve
+   to divide up this string value. The separator may be a string of any length.
+
+   As a special case, if the separator is the empty string, the string is split
+   up into individual characters; the length of the result array equals the
+   length of the string, and each substring contains one character.
+
+   If the separator is not supplied, then the result array contains just one
+   string, which is the string.
+
+   When the split method is called with one argument separator, the following steps are taken:
+
+   1.   Call ToString, giving it the this value as its argument.
+   2.   Create a new Array object of length 0 and call it A.
+   3.   If separator is not supplied, call the [[Put]] method of A with 0 and
+   Result(1) as arguments, and then return A.
+   4.   Call ToString(separator).
+   5.   Compute the number of characters in Result(1).
+   6.   Compute the number of characters in the string that is Result(4).
+   7.   Let p be 0.
+   8.   If Result(6) is zero (the separator string is empty), go to step 17.
+   9.   Compute the smallest possible integer k not smaller than p such that
+   k+Result(6) is not greater than Result(5), 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 go to step 14.
+   10.   Compute a string value equal to the substring of Result(1), consisting
+   of the characters at positions p through k1, inclusive.
+   11.   Call the [[Put]] method of A with A.length and Result(10) as arguments.
+   12.   Let p be k+Result(6).
+   13.   Go to step 9.
+   14.   Compute a string value equal to the substring of Result(1), consisting
+   of the characters from position p to the end of Result(1).
+   15.   Call the [[Put]] method of A with A.length and Result(14) as arguments.
+   16.   Return A.
+   17.   If p equals Result(5), return A.
+   18.   Compute a string value equal to the substring of Result(1), consisting of
+   the single character at position p.
+   19.   Call the [[Put]] method of A with A.length and Result(18) as arguments.
+   20.   Increase p by 1.
+   21.   Go to step 17.
+
+   Note that the split 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.
