• As an authenticated user, I can see a single poll by clicking on it in the list.
• As an unauthenticated or authenticated user, I can see the results of polls in chart form.
• As an unauthenticated or authenticated user, I can see and vote on respective poll.
• After submitting vote, the result should be updated in the chart.
• As an authenticated user, I can delete polls that I decide I don't want anymore by clicking on remove icon(or delete button) in the list.
• As an authenticated user, If I don't like the options on a poll, I can create a new option(custom).
