53 /*! Inner part of dictionary - glues together GUI and plugins
55 Backbone is responsible for managing plugins and dictionaries, starting
56 new searches and threads, merging search results from multiple dictionaries.
58 Each plugin may live in multiple instances - each with its own dictionary,
59 backbone must provide way to create them at start (with specific Settings) and
60 distinguich each ditionary.
