Particles will be created with a randomly generated direction between the minimum and maximum thresholds (which must be in counter-clockwise degrees) and will turn left or right each step depending on the relative direction change you specify.

Parameters

ind	integer	index of the particle type
min	double	minimum direction in counter-clockwise degrees, default is 0
max	double	maximum direction in counter-clockwise degrees, default is 0
incr	double	relative direction change each step, default is 0
wiggle	double	wiggling of the direction, default is 0

Return Values
