   can vote for any other state, in condition that both
   his state and the state to vote for are registered and participate.
   otherwise the vote operation is just ignored without any other notice.
   a Regular voter votes each time for a single state. This state gets 1 point
   for each voting. The regular voter can vote more than once, but no more than max allowed times for voting,
   which is defined when declaring the MainControl system. Default is 5.
   Moreover, he can vote all the times for the same state, or he can vote
   each time for a different state, in condition he does not exceed the allowed
   limit of max times of voting.
   a Judge voter can vote only ONCE, no more. all additions votings of his are
   just ignored without furthere notification.
   in contradiction to a regular voter, he can give a list of 1 to 10 different state names.
   the points given to the states are according to the order they are mentioned :
   first state gets 12 points, second 10 points, third 8 points and so on.
   if there less than 10 states, then only the given states get points, starting from 12,
   according to their order.
   if there are states that are not registered in the system, they are ignored.
   in any case, the points to every state are given regarding its absolute order number,
   no matter if previous states in the list are not legal.
   remark - we assume that the list for a Judge voter does not have states that appear
   more than once. No need to check this.
