/**
 * Common interface for document storage services in the cloud. This interface
 * supports most document services and provides some flexibility for
 * vendor-specific features and requirements via an optional $options array in
 * each method signature. Classes implementing this interface should implement
 * URI construction for collections and documents from the parameters given in each
 * method and the account data passed in to the constructor. Classes
 * implementing this interface are also responsible for security; access control
 * isn't currently supported in this interface, although we are considering
 * access control support in future versions of the interface.
