Log Message:
-----------
This version contains many changes and bug fixes:
+ Some classes have been moved to gridsim.turbo package.
+ The ParallelSpaceShared policy has been changed substantially and some bugs have been fixed. For example, the policy was not compressing the schedule properly when cancelling a gridlet. This could also lead to finding the wrong anchor for a job when the completion of a job matched the completion of another job and there was a big job starting at this completion time.
+ Some advance reservation features have been provided, but they are still being tested.
+ Improvements in the graphical user interface have been made.
+ Some changes in SimJava classes have been made to remove the animation and log capabilities that are not used by GridSim.

-/**
- * Look for a specific incoming event that matches a given event tag name and a
- * transaction id. Incoming events with a matching tag name <b>must</b>
- * contain a data object of type
- * <tt>long[]</tt>, where <tt>long[0]</tt> stores the transaction id.<br>
- * <tt>NOTE:</tt> This class can only be used for getting a reply or feedback
- * from a {@link gridsim.ARGridResource} entity regarding to a creation of
- * new reservation.
- * <br><br>
- *
- * This class is used by {@link eduni.simjava.Sim_system}
- * to select or filter an event already present in the entity's deferred queue
- * (incoming buffer), or used to selectively wait for a future event.
- * <br> <br>
- *
- * <b>An example on how to use this class:</b><br>
- * Imagine we have a scenario where <tt>RESOURCE_A</tt> sends one or more events
- * to <tt>Entity_B</tt> with different tag names and data objects.<br>
- * <tt>Entity_B</tt> wants to get an event that contains a create reservation
- * result with a transaction id of <tt>10</tt> in this example. <br>
- * Therefore, inside the <tt>Entity_B</tt> code:<br> <br>
- *
- * <code>
- *
- * ... // other code <br><br>
- * int transactionID = 10; <br>
- * Sim_event ev = new Sim_event(); <br>
- * FilterCreateAR filter = new FilterCreateAR(transactionID); <br>
- * <br>
- * // get an incoming event that matches a given transaction ID<br>
- * super.sim_get_next(filter, ev); <br>
- * <br>
- * // get the matching event data <br>
- * long[] data = (long[]) ev.get_data();
- * // data[0] contains transaction ID <br>
- * </code>
- * <br><br>
- *
- * <b>NOTE:</b>
- * <ul>
- * <li> both <tt>RESOURCE_A</tt> and <tt>Entity_B</tt> must be an instance of
- * {@link eduni.simjava.Sim_entity} class.
- * <li> <tt>RESOURCE_A</tt> <b>must</b> send the correct data object to
- * <tt>Entity_B</tt> for events with a matching tag name. <br>
- * The event data object with a matching tag name
- * <b>must</b> be of type <tt>long[]</tt>, where
- * <tt>long[0]</tt> contains the transaction id.
- * <li> if no incoming events match the given condition, then
- * {@link eduni.simjava.Sim_entity#sim_get_next(Sim_predicate, Sim_event)}
- * method will wait indefinitely.
- * </ul>
