 /**
 31  
  * Default implementation of a HiLo ID generator that allows to use another
 32  
  * (non-HiLo) ID generator for generating the "hi" part of the ID. The delegate
 33  
  * must increment its ID is discrete steps > 1, so that the gaps can be filled
 34  
  * with "lo" IDs.
 35  
  * <p>
 36  
  *     Example:
 37  
  * </p>
 38  
  * <pre>
 39  
  *     Hi IDs: 0, 100, 200, 300 (increment = 100)
 40  
  *     Lo IDs: 1,2,3,...,100,1,2,3,....
 41  
  *     Resulting ID (Hi + Lo): 1,2,3,99,100,101,102,...
 42  
  * </pre>
