Finding nodes by type or id about php-svg

[meyfa]

There is no such feature as of yet, but it would be a good addition. I will try to draft something up as soon as possible.

I implemented getElementById($id) (936d22c) and getElementsByTagName($tagName) (2283a21). They behave exactly like their JavaScript counterparts.

Example:

$image = SVGImage::fromFile('file.svg');
$doc = $image->getDocument();

$byId = $doc->getElementById('foobar');
// $byId is now set to the element with id="foobar"

$byTagName = $doc->getElementsByTagName('rect');
// $byTagName is now set to an array with all <rect /> nodes

Note that getElementById can only be invoked on the document (as usual, since ids are unique across the document). getElementsByTagName can be invoked on any node.
