JSONPath extension

Hi!

My name is Viktor Djupsjöbacka and I'm a Lead Developer at Supermetrics. 
In recent months, we've revived an old, unpublished PHP extension 
project for using JSONPath notation in array data lookups. Together with 
the original project creator, Mike Kaminski, we've rewritten the whole 
extension, enabling it for use in modern PHP versions, improving 
performance and maintainability, and covering it with tests. We're now 
at the point where we believe the extension is ready for use in the 
wider community as a 'jsonpath' PECL package.

You can find the code at 
https://github.com/supermetrics-public/php-ext-jsonpath.

Best regards,
Viktor
