Implement internal (between accounts) orders
Created by: bnjbvr
Random ideas (stolen from others, of course):
- predict the evolution of the balance during the month and send micro-wires to savings accounts according to this
- every time a CB operation is being done, round the transaction to the nearest above, and send the difference to a savings account. E.g. if a buy a pair of socks for 5.37e, send 0.63e to my savings account.
