/**
* Data access interface
*
* This interface specifies data access methods libomb needs. It should be
* implemented by libomb users. OMB_Datastore is libombs main interface to the
* applications data. Objects corresponding to this interface are used in
* OMB_Service_Provider and OMB_Service_Consumer.
*
* Note that its implemented as a class since OAuthDataStore is as well a
* class, though only declaring methods.
*
* OMB_Datastore extends OAuthDataStore with two OAuth-related methods for token
* revoking and authorizing and all OMB-related methods.
* Refer to OAuth.php for a complete specification of OAuth-related methods.
*
* It is the users duty to signal and handle errors. libomb does not check
* return values nor handle exceptions. It is suggested to use exceptions.
* Note that lookup_token and getProfile return null if the requested object
* is not available. This is NOT an error and should not raise an exception.
* Same applies for lookup_nonce which returns a boolean value. These methods
* may nevertheless throw an exception, for example in case of a storage errors.
*
* Most of the parameters passed to these methods are unescaped and unverified
* user input. Therefore they should be handled with extra care to avoid
* security problems like SQL injections.
