Multi-provider, extensible authentication framework

Package installation is handled by Composer.

• If you haven't already, please install Composer
• Create composer.json in the root of your project:

{
    "require": {
        "dreamfactory/oasys": "~0.4"
    }
}

• Run composer install
• Require Composer's vendor/autoload script in your bootstrap/init script

• Feedback is welcome in the form of pull requests and/or issues.
• Contributions should generally follow the strategy outlined in "Contributing to a project"
• Please submit pull requests against the develop branch

• This code is an amalgamation of four different libraries that I've been carting around for years. It wouldn't have been possible if there weren't so many poorly crafted generic authentication systems available. ;)
