Simple Event Example

This example demonstrates the various ways of playing an event.

#### Explosion Event ####
This event is played as a one-shot and released immediately after it has been
created.

#### Looping Ambience Event ####
A single instance is started or stopped based on user input.

#### Cancel Event ####
This instance is started and if already playing, restarted.
