Example

import Cache, {CacheDependency} from 'cache-net'

const cache = new Cache(3) // max size is three items
const key = {id: 'three', hello: 'world'} // can be any plain object

cache.set('one', 1)
cache.set('two', {a: 1, b: {c: 'hi'}})
cache.set(key, 3, {dependencies: new CacheDependency('two')})
cache.set('four', {slidingExpirationMsec: 5000}) // will be removed in 5 sec if not accessed

let value = cache.get('one') // undefined (deleted because of size limit)
value = cache.get('two') // { a: 1, b: { c: "hi" }}
value = cache.get(key) // 3

cache.remove('two') // will also remove dependent item referenced by "key"
