Implements in-memory [cache with write-back strategy](https://en.wikipedia.org/wiki/Cache_(computing)#Writing_policies)

(a cache with expiration).

An expiration callback(`expireFn`) will be called when record is expired.

### Features

* Thread-safe.

* Per-key or global TTL.

* Can trigger a custom callback on key expiration(could be used as Pub/Sub with aggregation).

* Can trigger a custom callback on key collisions(e.g. for aggregating metrics). 

By default, will overwrite value.

* Graceful shutdown(using context). Will call expiration callback for all records,

ignoring they TTL.

### Install

`go get github.com/vtopc/wcache`

### TODO

* Optional auto-extending expiration on `Get` and/or `Set`.
