Test purpose
- Create a Net entity with draggable Particles
- Create a range of other entitys of different types, and position them on the Net entity by reference to the Net's Particle objects.
- Check that when the Net's particles are dragged, the other entitys will update their positions accordingly.
Touch test: should work as expected. Known issue: moving the pins is inconsistent (because particle drag zones are too small on device screens?) Also, the particle system will often fail in lower-spec devices
