### Spiral Particles v0.4
#######################
### USAGE
####################
### - run s@Spiral_Particles def:Location|Effect|Length|Radius|Rotation
### Location: origin (for example, <player.eye_location>)
### Effect: the particle effect in the format "effect,data,qty,offset" (if not specified, flame,0,1,0)
### Length: the distance in blocks to go before stopping (if not specified, 20)
### Radius: radius of the spiral (if not specified, 1)
### Rotation: the angle to start the spiral from (if not specified, a decimal between 0 and tau)
