View Count : Tell how much we have to transfer

[fprovostpoulin]

It would be nice to have another column telling us how many we should transfer to optimize our candies. Lets say I have 112 candies and 20 pidgey, I'd like the app to tell me I should transfer :

floor(112/12) = 9 + 4 free
20 piedgey - 9 = 11 pidgey free
if I transfer 12-4 free = 8, i can evolve evolve 1 more,
So the number of pidgey I really have to transfer is 11-8 = 3
(Also, a column with how many I can evolve Considering transfers could be nice)
