### SmartMap
Like WeakMap but can also store values using primitive keys
Example usage:
import { SmartMap } from "@thalesrc/js-utils"; const aMap = new SmartMap(); aMap.set("foo", "foo"); aMap.set(1, "thales rocks"); console.log(aMap.size) // 2 aMap.set({}, "thales rocks again"); console.log(aMap.size) // 2 const anObject = {}; aMap.set(anObject, "thales rocks again and again"); console.log(aMap.size) // 3 console.log(aMap.get(anObject)) // "thales rocks again and again"K Typeof Key
