  ==========
  
  This provides the `lru` package which implements a fixed-size
  thread safe LRU cache. It is based on the cache in Groupcache.
  
  Documentation
  =============
  
  Full docs are available on [Godoc](http://godoc.org/github.com/hashicorp/golang-lru)
  
  Example
  =======
  
  Using the LRU is very simple:
  
  ```go
  l, _ := New(128)
  for i := 0; i < 256; i++ {
      l.Add(i, nil)
  }
  if l.Len() != 128 {
      panic(fmt.Sprintf("bad len: %v", l.Len()))
  }
  ```
