• Split Account service into:
  • Account service taking care of account information.
  • AccountApi service managing account related Api calls.
• Change all use cases of Send to Transfer.
• Move delegate service and forging service and peer under services/api directory.
• Rename $peers service to Peers.

I don't like that the names of services are capitalised. They are not instantiated with new. I'd rather have account, peers, ... then Account, Peers, ...

Some resources on that:

@slaweet The two resources you've linked are not using the same convention for services and factories. but I'm ok with cameCase.
