Transaction Completed Event domain event handler

if (type is logon) then ignore
else then add a new event to merchant statement aggregate

Flow

1. Transaction Completed arrives
2. merchant is rehydrated
3. Work out the next statement date (how is this done), do we feed statement generated events back into the merchant to update the statement date? Statements will be monthly!!
4. Check if this statement exists already (use date to guid) (StatementCreatedEvent)
   4.1) If statement doesnt exist then create (MerchantStatementAggregate-GUID)
5. Add transaction to statement (ensure same transaction is not added more than once)
6. Every day statement generator process runs, closes off the statement (StatementGeneratedEvent)

Statement Generated Event domain event handler

This will update the last statement date at the merchant (need some way of duplicate checking, maybe hold statement ids in the merchant state)
