 * getComponents - returns an array of all attached script-enabled components on this ItemStack
 * NumberRange
 * A class to describe a random value between a min and max number
 * Property min - the minimum value in the range
 * Property max - the maximum value in the range
 * next - returns a random number between min and max

 * Property damage - gets or sets the current damage on the ItemStack
