Provides a HTML Canvas to generate HTML. Inspired by Smalltalk Seaside HTMLCanvas.

Usage:

(new HTML)
  ->div(fn($h) => $h->span('Hello')
                    ->span('World'))
   ->a(['class' => 'important', 'href' => 'here.org'],
       'I\'m coming');

Will output :

<div>
  <span>Hello</span>
  <span>World</span>
</div>
<a class="important" href="here.org">I\'m coming</a>

All HTML functions are handled by __call so all method names will be converted to an HTML tag with the same name.

Arguments:

• Optional first argument is an array of key/value pairs that represents HTML tag attributes
• Optional next argument can be either a string for text content, or a Closure for a nested tag

Other functions:

• text : renders text content, useful for chaining
• bi : renders bootstrap icons
