## BaseMessage
BaseMessage is a basic message model, basis of the whole protocol. It is used for a very easy protocol extension process.
BaseMessage scheme:
```
id (string) - identifier of message (used to track the request-response chain)
type (string) - type of message (used to determine which extension this message belongs to)
from (EntityID) - from which entity this message is send
to (EntityID) - message recipient
ok (boolean) - operation success indicator (used to determine if errors was happened when processing request)
payload (Map<K,V>) - message payload (used to store extra information in message, list of permissible fields in the payload are depends on "type" field)
```
