Serialization

We are waiting for the 2.0 JSON serialization specification from Microsoft, before finalizing our serialization. For now, we are still mostly using the 1.9 serialization.

EGK can use both JSON and Protocol Buffers for serialization. Protobuf is a binary format that takes roughly half the space of JSON for the same information. EGK includes .proto files for all the relevant data formats, which constitutes a well defined and compact schema for EG serialization.
