Simple function memoization over Erlang ETS / JavaScript Map for Gleam

```sh

gleam add glemo

```

```gleam

import glemo

pub fn main() {

  // init caches on application startup

  glemo.init(["my_cache"])

  // try get from cache

  // on first attempt item not exists in cache

  // fallback function will be called

  // result of fallback function will be placed to cache, function argument is used as key

  1

  |> glemo.memo("my_cache", fn(x) { x + 1 }) // 2

  // now value returned from cache, fallback function ignored

  1

  |> glemo.memo("my_cache", fn(x) { x + 1 }) // 2

  // invalidate cache item by specific key

  glemo.invalidate_specific(1, "my_cache")

  // invalidate all cache

  glemo.invalidate_all("my_cache")

}

```
