lrucache

Size-limited LRU cache in Lua

`local lrucache = require'lrucache'`

LRU cache limited by an abstract size. Values can have different sizes. When a new value is put in the cache and the cache is full, just enough old values are removed to make room for the new value and not exceed the cache max size.

`cache:value_size(val) -> size`	get value size (to be overriden; returns 1)
`cache:free_size() -> size`	size left until `max_size`
`cache:get(key) -> val`	get a value from the cache by key
`cache:remove(key) -> val`	remove a value from the cache by key
