""" A voting round control implant.
How to start a voting? Examples:
'create poll' will start a dialogue. I will ask for:
1) the topic of the poll,
2) a code to reference the poll and
3) the number of hours it will last.
How to vote for a voting round with code *SDT1*? Examples:
'vote SDT1 +1'
'vote SDT1 0'
'vote SDT1 -1'
How to get the result for the round?
'show results of voting round SDT1'
How to close the round?
'close voting round SDT1'
'close poll SDT1'
How to see the polls?
'show open polls'
'show all polls'
The round codes must be unique during all the bot's life (or its database).
The round codes have a maximum of 10 characters and should be all capital letters or numbers.
Generally you can use the term 'voting round' as well as 'poll'.
