Entity Extras for ImpactJS
- PinTrigger: This entity calls the triggeredBy method of one or more
targets when it and another entity of a specific collision type overlap at
the almost-same position.
- Blocker: This entity stops the movement of all all triggering entities
and releases them after a specified duration.

- Just plop those entities you need into your lib/game/entities folder. Be
careful to not overwrite existing files.
- Use in WM at will. A test level is included with the pack, inside
./lib/game/levels.
- Read the source code headers to better understand usage and options.
