 /**
  * Pull changes from Active Directory for a given query
  *
  * Use this method to set up a search query and later get all changed objects
  * for that query. This method returns a special {@link Delta} object that preserves
  * your search configuration and you use this object for consequent
  * searches. It also contains your search results. When you run the method for the first time,
  * it behaves as if you performed just an ordinary search, but on consequent searches,
  * it only returns objects that were modified or deleted since you last ran the search query.
  *
  * <br>
  *
  * <p class='alert'>Note that due to the way this feature is implemented it is impossible to
  * search for objects where only specific attributes have been modified - the method returns all objects
  * that were modified in any way since your last execution and it is your task to determine if
  * the changes happened on attributes that you are interested in.</p>
  * <br>
  *
  * This method takes two possible forms of arguments:<br>
  * When you run it for the first time, you pass the search parameters
  * as for any other ldap search query - the search filter, the list of attributes to be
  * returned and a fully configured {@link Link} instance.
  *
  * <br>
  *
  * For all consecutive executions, you only pass the {@link Delta} instance
  * that you got when you ran the method for the first time and, again, a configured {@link Link}
  * instance.
  *
  * <h2>Example:</h2>
  * To watch for changes on all users in your domain:
  * <code>
  * // Establish connection to your directory server
  * $link = new Link( 'example.com' );
  * $link->bind( 'admin@example.com', 'SecretPwd' );
  *
  * // When called for the first time for a particular query, you get
  * // an instance of Delta class - this instance contains the results
  * // of your query as well as all the information/state necessary
  * // to perform subsequent queries to get all changes for that resultset
  * $delta = Task::changes( '(objectcategory=person)', ['mail', 'name', 'memberof'], $link );
  * $result = $delta->result;	// Here's where the actual data is
  * // Do something with result...
  *
  * // Now it's time to store the $delta instance someplace safe so we can get
  * // changes for this query at a later time - you should serialise the instance
  * // and store it somewhere - i.e. in a database or on disk
  * file_put_contents( 'my_query_state.txt', serialize( $delta ) );	// Always serialise!
  *
  * // Many moments pass...
  * // In another script, far, far away...
  *
  * // It's time to see which objects have been modified since our last run
  * // Connect to ldap again
  * $link = new Link( 'example.com' );
  * $link->bind( 'admin@example.com', 'SecretPwd' );
  *
  * // Get the previous query state from the file
  * $delta = unserialize( file_get_contents( 'my_query_state.txt' ) );
  * // And get all the objects that have been changed since we last
  * // run the changes method, but this time we only pass in
  * // the instance of Delta class - it contains all the information
  * // about our previous query so we don't have to configure it again
  * $delta = Task::changes( $delta, $link );
  * $result = $delta->result;	// Changed objects are here again!
  *
  * // Notice that now we have a new instance of the Delta class in the
  * // $class variable - reflecting the fact that we just ran the query again
  *
  * // And so the story continues on and on...
  * </code>
  *
  * <h2>Things you should know</h2>
  * <ul>
  * <li>You must always connect to the same domain controller for a particular query,
  * otherwise you will receive the full resultset on each run</li>
  * <li>To track deleted objects, all returned objects have an <i>isDeleted</i>
  * {@link Attribute} automatically that you can use to check if that object has been deleted</li>
  * <li>You cannot use BaseDN overrides with this feature at this time
  * ( this might be implemented in the future )</li>
  * </ul>
  *
  * @return		Delta		Object containing the state and data of the changes
  *
  * @see			<a href="http://msdn.microsoft.com/en-us/library/ms677627.aspx">MSDN - Polling for changes using usnChanged</a>
