If <code>start</code> is omitted, it's treated as 0.<br />
If <code>start</code> < 0, the index is counted from the end of the string.<br />
If <code>start</code> >= the string's length, an empty string is returned.<br />
If <code>end</code> is omitted, or if <code>end</code> >= the string's length, extracts to the end of the string.<br />
If <code>end</code> < 0, the index is counted from the end of the string.<br />
If <code>end</code> <= <code>start</code> after normalizing negative values, an empty string is returned.
