Peer Value Distributer
Given an array, return a new array with the same keys and values distributed
randomly and evenly amongst the peers in the specified batch quantity., (*1)
, (*2)
For example, say you have a group of 15 book authors. You want each author to
review 3 of their peers' work. This function will randomly assign each
author 3 of its peers to read., (*3)
- Every book is reviewed exactly 3 times.
- No one will review any book more than once.
- No one will review their own book.
The natural maximum distribution count is n-1
so if you specify a count larger than that,
it will be ignored and the largest possible count will be used instead., (*4)
e.g. if you distribute those 15 books with a count of 20,
it will be ignored and instead every author will be assigned the maximum
of 14 peer books to review., (*5)
