A SKEmitterNode object is a node that automatically creates and renders small particle sprites. Particle sprites are privately owned by Sprite Kit—your game cannot access the generated sprites. For example, this means you cannot add physics shapes to particles. Emitter nodes are often used to create smoke, fire, sparks, and other particle effects. Available in iOS 7.0 and later.

SKEmitterNode: modify properties like velocity and angle for individual particles?
The SKEmitterNode in SpriteKit lets you change particle properties, but it's not clear how you change properties for specific particles.
For instance, if we want particles to radiate in a circle shape, it seems we need to dictate the angle and speed…
