Feature request: installation with composer and packagist

[yookoala]

The defacto standard of PHP library is to publish it on Packagist.org and allow installation with composer install vendor-name/package-name command. Then the composer autoloader will do the heavy loading to include proper file. Also the composer will know when a new release is available for update.

This would provide compatibility to all popular web frameworks (e.g. Laravel, Symfony, Drupal).

To do this, this package needed to:

• Update composer.json to add package name and proper PSR-4.
• Publish a version (i.e. tag a commit with a semantic versioning tag on GitHub)).
• Submit this git repository to packagist.

#8 is a step forward to this goal but some more steps will be needed.
