Add support for non-standard fields, fixes #19
Add license
Update README.md

Updated installation instructions via composer to use the `composer require` command without specifying a version.
This is the new recommended way of providing this information and it leads to composer picking the proper version constraint (i.e ~1.2), updating the `composer.json` and running install, all in one command.
