Pass zero arguments to get/set/et al (ability to access current path)

[katowulf]

It's not possible to access the current or root path using get/set/et al.

Example:

$fb = new Firebase\Firebase(array(
  'base_url' => 'https://INSTANCE.firebaseio.com/phptest',
  'token' => SECRET,
),new GuzzleHttp\Client());

// this generates an error and I can't access the phptest/ path, nor would I be able to access
// the root path in a Firebase
var_dump($fb->get());

Hi @katowulf, I've tried to implement zero argument get and delete member functions and single argument setter, updater and pusher member functions. Can you confirm this issue fixed?
