**Only merge after #9  is merged**
Just linking #11 
It's simple, if you don't **force** a request (given on class constructor), we create one, based on the current Request.
The class `Zend\Http\PhpEnvironment\Request` instantiated on constructor, create this request if you don't pass a `RequestInterface` object. Them, We maintain the class flexible and can create resource based on the Request at runtime. We can change the things. Haven't wrong things here.
