/**
 * 
 * Describes an adjustment based on the difference between the value of the
 * aggregated CloudWatch metric and the breach threshold that you've defined for
 * the alarm.
 * 
 * 
 * For the following examples, suppose that you have an alarm with a breach
 * threshold of 50:
 * 
 * 
 * - 
 * 
 * If you want the adjustment to be triggered when the metric is greater than or
 * equal to 50 and less than 60, specify a lower bound of 0 and an upper bound
 * of 10.
 * 
 *  
 * - 
 * 
 * If you want the adjustment to be triggered when the metric is greater than 40
 * and less than or equal to 50, specify a lower bound of -10 and an upper bound
 * of 0.
 * 
 *  
 * 
 * 
 * There are a few rules for the step adjustments for your step policy:
 * 
 * 
 * - 
 * 
 * The ranges of your step adjustments can't overlap or have a gap.
 * 
 *  
 * - 
 * 
 * At most one step adjustment can have a null lower bound. If one step
 * adjustment has a negative lower bound, then there must be a step adjustment
 * with a null lower bound.
 * 
 *  
 * - 
 * 
 * At most one step adjustment can have a null upper bound. If one step
 * adjustment has a positive upper bound, then there must be a step adjustment
 * with a null upper bound.
 * 
 *  
 * - 
 * 
 * The upper and lower bound can't be null in the same step adjustment.
