Rank by Integer Buckets

Re-rank objects by the value of an integer property. Every object's score is boosted proportionally to the size of the bucket it belongs to. Buckets are defined as integer ranges of a given size. For example, with values [0,2,3,9,10,12,50,70] and bucket size 10, the following buckets are created:

1. [0,2,3,9]
2. [10,12]
3. [50]
4. [70]

and all items in bucket 1 will get a score boost 4 times as large as those in buckets 3 and 4

• SOURCE [OBJ,INTEGER]: the list of objects to rank, with an associated integer value

• RESULT [OBJ,INTEGER]: ranked objects

• Bucket size: for each input integer i, the resulting bucket identifier is given by i / Bucket size
