This API aims to expose access to these services in a way that is intuitive
and easy to use for PHP enthusiasts. The ServiceBuilder instance exposes
factory methods which grant access to the various services contained within
the API.
Configuration is simple. Pass in an array of configuration options to the
constructor up front which can be shared between clients or specify the
options for the specific services you wish to access, e.g. Datastore, or
Storage.
Please note that unless otherwise noted the examples below take advantage of
Application Default Credentials.
