Simple WeakMap utilities

Map Utils

Simple Map based utilities:

• pathGet - takes a map instance and an array of keys - traverses the map and returns the value
• pathSet - takes a map instance, an array of keys and a value - traverses the map (creating new Map instance if necessary) and sets the value at the
  leaf of the map
• memoize - takes a function and returns a new memoized function using a Map structure for the result cache. Currently there is no limit to the size of the cache. However we use a WeakMaps so if there is no strong reference to all the arguments, then the result will be garbage collected
