Added support for subscriptions to the real-time API

[philperusse]

I've added support for the real-time subscriptions API.
I've also added two files to show how it works. Pretty straight forward.

Great work !

I had to modify the _makeCall function to make the delete subscription methods works.

Line 508 of your file

$apiCall = self::API_URL . $function . $authMethod . (('GET' === $method || 'DELETE' === $method) ? $paramString : null);

It seems that the parameters have to be send through the query string when the DELETE method is used.

+1! but the coding standards are somehow … different then the original version ;) indendation seems a little bit broken.

Any reason why this was never merged or updated?

This repo seems to be stale. I've made a fork and updated it with some new changes in Instagram's API: https://github.com/florianbeer/Instagram-PHP-API

oh snap! I thought that fork was a recent thing you were referring to! Thanks @florianbeer

@cosenary can we get close this in favor of #204 ?
