<div class="block">An unordered map where the keys are ints and values are floats. This implementation is a cuckoo hash map using 3 hashes, random
walking, and a small stash for problematic keys. Null keys are not allowed. No allocation is done except when growing the table
size.
<br>
<br>
This map performs very fast get, containsKey, and remove (typically O(1), worst case O(log(n))). Put may be a bit slower,
depending on hash collisions. Load factors greater than 0.91 greatly increase the chances the map will have to rehash to the
next higher POT size.
