Collates (GCToolKit API 3.7.0 API)

```
@Retention(RUNTIME)
@Target(TYPE)
public @interface Collates
```
An implementation of an Aggregation collates data from an Aggregator. This annotation is used on an Aggregation to tell GCToolKit which Aggregator produces the data the Aggregation collates.
In this example, there is a PauseTimeAggegator which receives pause time events from GCToolKit. The PauseTimeAggregator extracts the cause, the time the event occurred, and the duration of the event and calls the PauseTimeAggregation method.
An implementation of PauseTimeAggregation is able to collate the data in a way that makes sense for how the data is to be viewed. For example: one may want to summarize the data as a histogram, or one may want to collect a series of data for plotting.
```
 @Aggregates({EventSource.G1GC. EventSource.Generational, EventSource.ZGC, EventSource.Shenandoah})
 public class PauseTimeAggregator extends Aggregator<PauseTimeAggregation> {
     ...
 }
 @Collates(PauseTimeAggregator.class)
 public interface PauseTimeAggregation extends Aggregation {
     ...
 }

 public class PauseTimeSummary implements PauseTimeAggregation {
     ...
 }

 public class PauseTimeGraph implements PauseTimeAggregation {
     ...
 }
 
```
