Adds a new, cleaned up, HashMap implementation. * Uses Robin Hood Hashing (https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing). * Keeps elements in a double linked list for simpler, ordered, iteration. * Allows keeping iterators for later use in removal (Unlike Map<>, it does not do much for performance vs keeping the key, but helps replace old code). * Uses a more modern C++ iterator API, deprecates the old one. * Supports custom allocator (in case there is a wish to use a paged one). This class aims to unify all the associative template usage and replace it by this one: * Map<> (whereas key order does not matter, which is 99% of cases) * HashMap<> * OrderedHashMap<> * OAHashMap<>
