PSR4 autoloading directory

[RobinRadic]

If i am not mistaken, the current directory structure and autoloading definition is not according to http://www.php-fig.org/psr/psr-4/.

{
    "autoload": {
        "psr-4": {
            "Caffeinated\\Beverage\\": "src/Caffeinated/Beverage/"
        }
    }
}

Should be "Caffeinated\\Beverage\\": "src/"

Directory structure should be

src
src\Arr.php
src\Str.php
config
config\config.php
composer.json
