-/**
- * ContentSearch receives messages named INBOUND_MESSAGE and sends messages
- * named OUTBOUND_MESSAGE.  The data of each message is expected to look like
- * { type, data }.  type is the message's type (or subtype if you consider the
- * type of the message itself to be INBOUND_MESSAGE), and data is data that is
- * specific to the type.
- *
- * Inbound messages have the following types:
- *
- *   AddFormHistoryEntry
- *     Adds an entry to the search form history.
- *     data: the entry, a string
- *   GetSuggestions
- *     Retrieves an array of search suggestions given a search string.
- *     data: { engineName, searchString, [remoteTimeout] }
- *   GetState
- *     Retrieves the current search engine state.
- *     data: null
- *   GetStrings
- *     Retrieves localized search UI strings.
- *     data: null
- *   ManageEngines
- *     Opens the search engine management window.
- *     data: null
- *   RemoveFormHistoryEntry
- *     Removes an entry from the search form history.
- *     data: the entry, a string
- *   Search
- *     Performs a search.
- *     Any GetSuggestions messages in the queue from the same target will be
- *     cancelled.
- *     data: { engineName, searchString, healthReportKey, searchPurpose }
- *   SetCurrentEngine
- *     Sets the current engine.
- *     data: the name of the engine
- *   SpeculativeConnect
- *     Speculatively connects to an engine.
- *     data: the name of the engine
- *
- * Outbound messages have the following types:
- *
- *   CurrentEngine
- *     Broadcast when the current engine changes.
- *     data: see _currentEngineObj
- *   CurrentState
- *     Broadcast when the current search state changes.
- *     data: see currentStateObj
- *   State
- *     Sent in reply to GetState.
- *     data: see currentStateObj
- *   Strings
- *     Sent in reply to GetStrings
- *     data: Object containing string names and values for the current locale.
- *   Suggestions
- *     Sent in reply to GetSuggestions.
- *     data: see _onMessageGetSuggestions
- *   SuggestionsCancelled
- *     Sent in reply to GetSuggestions when pending GetSuggestions events are
- *     cancelled.
- *     data: null
