We'd like to experiment with BitShares blockchain and research the possibility of extending accounts objects with with additinal fields.

We have tried to extend account_create_operation fields in wallet.cpp and add field in account_object.hpp abd have some success writing data to blockchain but we can't to get it back via wallet or RPC API.

Moreover, we see the extention struct, but there is the lack of documentation about it. Is it expected to be used in such cases?
