Memoization of synchronous and asynchronous functions

Tasks:

• see examples
• implement time expiration cash
• implement memoize with max records count and removing least used
• implement memoize with max total stored data size
• implement universal memoize compatible with both sync and async function
• implement functional object with following properties methods and events:
  • memoized.clear() - clear cache
  • memoized.add(key, value) - add value to cach
  • memoized.del(key) - remove value from cach
  • memoized.get(key) - returns saved value
  • memoized.timeout: Number - cache timout
  • memoized.maxSize: Number - maximum cache size in bytes
  • memoized.maxCount: Number - maximum cache size in item count
  • memoized.on('add', Function)
  • memoized.on('del', Function)
  • memoized.on('clear', Function)
