- the proxy should always be used to access other parts of Ghost, including the urlService etc - use consistent ES6 style for requires - minimise use of lodash where possible - remove circular dependency between proxy and template util - End goal here is to enforce that the only link between helpers + the rest of Ghost is the proxy
