CompletedTwoProbeChainHT: In a normal chaining approach, keys hash to exactly one index and

the key$/$value pair must reside in the list at that particular index. In this new approach, we will instead

calculate two hashes, that indicate two dierent indices, and then add the new key$/$value to whichever of

two lists, at the two indices, is the shortest. The result is that the chains will end up being shorter since we

split in half where the key$/$value pairs are placed.
