    Determine the rough number of cache pruning cycles since the cache statistics were last reset.
    For the LocalCache implementation, this refers to the number of times that the prune() method is executed.
    
    Specified by:
    
    getCachePrunes in interface CacheStatistics
    
    Returns:
    
    the total number of cache pruning cycles (since that last statistics reset)
