* Base class for a driller events. All events collected in aggregators should use this class as a base.

|
|
* IMPORTANT: It's very important to note that DrillerEvents will NEVER be removed during a driller session
|
|
* this allows you to RELY on the fact that data which the event contains will be present at all times. This is important
|
|
* because it's heavily used to support StepBackward/StepForward in sequential driller events (almost all driller events are deltas
|
|
* and in that sense they are sequential - we can't just jump to a state directly).
