Flexible "id" arribute value rather than fixed "toc"

[KEINOS]

TL; DR

Add a method that changes the "id" attribute value from "toc" to ad hoc value somewhat like below.

<?php
require_once __DIR__ . '/vendor/autoload.php';

$text_markdown = file_get_contents('SAMPLE.md');

$Parsedown = new \ParsedownToC();

// Add attributes
$Parsedown->setAttributeID('toc');

$html = $Parsedown->text($text_markdown);
echo $html . PHP_EOL;

TS; DR

In the sample at README.md the parsed ToC is parenthesized with DIV tags with id="toc" attributes as below. But I want to change the "id" attribute value to another.

<div id="toc"><ul>
<li><a href="#One">One</a><ul>
<li><a href="#Two">Two</a></li>
</ul>
</li>
<li><a href="#One2">One2</a></li>
</ul></div>
<hr />
<h1 id="One" name="One">One</h1>
<p>Something about One</p>
<h2 id="Two" name="Two">Two</h2>
<p>Something about Two</p>
<h1 id="One2" name="One2">One2</h1>
<p>Something about One2</p>

Sample code

<?php
require_once __DIR__ . '/vendor/autoload.php';

// Sample Markdown with '[toc]' tag included
$text_markdown = file_get_contents('SAMPLE.md');

$Parsedown = new \ParsedownToC();

// Parses '[toc]' tag to ToC if exists
$html = $Parsedown->text($text_markdown);

echo $html . PHP_EOL;

$ cat SAMPLE.md
[toc]
