PollPost: o This subtype of Post is different in that it can be "reacted" to in two ways. This post should still be displayed with the emoji counters, but users can also submit a String answer. These will typically be a single word and can be anything! A PollPost should have a poll question and answers to the poll question as its content section. o Notice the answers contain a count next to them, and they are not sorted. You can use the StringIntPair class provided to simplify your collection of poll answers in PollPost
