Noticed adjustments to be made while looking at Game Loop

[icharette]

1. In buying resources, there should be the option to not buy resources.
2. In buying resources, there should be the option to buy a specific number of tokens at a time.
3. In buying cities there should be the option to not buy cities.
4. When showing the cities available, maybe it could show cities available to purchase to a specific player : (if adjacent or something)
5. When adding the resource purchased to the power plant : need to check if the power plant needs resource or not (rn it seems to still add it)
6. In Auction : not checking if enough elektros, the wallet goes into negative numbers.
7. In cities purchase : show,according to step, the new price of the cities available
8. Set max number of powerplants owned by player
9. Error in choosing city to buy; once you make a mistake in typing, it says everything else is a city not available in the region, even though you type the same thing.
10. Auction will not loop in the main game loop, after doing it once it will just skip. (I think it has to do with the player.size() while() condition)
11. Even if the sort method is called in the Auction method, the powerplant market is still not sorted. In my main of A2 (main_part4), it is working though. (pointer problem?)
12. *Do we implement the specifics of the powerplant MARKET according to the Step # in the Game ? The lab dude didn't inquire about it last time... It is a little tricky to add it since, depending on WHEN the Step3 card is drawn, the power plant market will be quite different.
