+`net/http` request rate limiter based on the Sliding Window Counter pattern inspired by
+CloudFlare https://blog.cloudflare.com/counting-things-a-lot-of-different-things.
 
 The sliding window counter pattern is accurate, smooths traffic and offers a simple counter
 design to share a rate-limit among a cluster of servers. For example, if you'd like
 to use redis to coordinate a rate-limit across a group of microservices you just need
-to implement the httprate.LimitCounter interface to support an atomic increment
