Added

• Standardized library API and documentation for @dicy/core and
  @dicy/client.
• JSON-RPC server and client implementing library API.

Changed

• Use TypeScript instead of Flow.
• All events are now sent to the log as regular log events, some with severity
  level of trace if they are not of interest to most users.
• Replaced --save-events with --save-log command line option since all
  events have been merged into log entry events.
• Log events can now contain multiple log messages.
• Primary interface to DiCy libraries is now through BuilderCacheInterace
  implementation instead of direct access to builder.

Removed

Fixed

  interface are now protected from cache cleaning.
