balgarath / ruby-counter-class

2 classes, Counter and BucketCounter, both extensions of Hash. Counter will increment a key by 1 each time something is added. Bucket counter supports integer intervals. You can set an interval (example) 1-10, and adding any number between 1 and 10 will increment that bucket
