This updates the installation and updating section of the README.md files in the various packages to call out the module they are a part of and instruct the consumer to use the standard go tooling instead of the old, and no longer correct, package-based 'go get -u' instructions.

lru
Package lru implements generic least-recently-used caches with near O(1) perf.
LRU Cache
A least-recently-used (LRU) cache is a cache that holds a limited number of items with an eviction policy such that when the capacity of the cache is exceeded, the least-recently-used item is automatically removed when inserting a new item. The meaning of used in this implementation is either accessing the item via a lookup or adding the item into the cache, including when the item already exists.
External Use
This package has intentionally been designed so it can be used as a standalone package for any projects needing to make use of well-tested and concurrent safe least-recently-used caches with near O(1) performance characteristics for lookups, inserts, and deletions.
Installation and Updating
This package is part of the github.com/decred/dcrd/lru module. Use the
standard go tooling for working with modules to incorporate it.
Examples
-
Basic Cache Usage Demonstrates creating a new cache instance, inserting items into the cache, causing an eviction of the least-recently-used item, and removing an item.
-
Basic KV Cache Usage Demonstrates creating a new k/v cache instance, inserting items into the cache, causing an eviction of the least-recently-used item, and removing an item.
