+* Description:
+* This class extends WebChromeContainerSnippet class to hold the
+* content view toolbar buttons. Showing/Hiding of the sub-chrome snippets in response to
+* the button selection is not entirely done here as we have a hybrid html-native design.
+* MostVisited: Show/Hide is handled in handleMVButton.
+* Menu: Show is handled in Javascript. Hide is handled here.
+* Zoom: Show/Hide is handled here. Zoom action buttons
+* Note: Most Visited is native while Menu and Zoom are html based. All three of them need to 
+* be dismissed if the user taps anywhere else on the screen. Since mv is native, it handles
+* all mouse events and dismisses itself. Zoom/Menu are created as PopupChromeItem which receives
+* the mouse events in its event filter and emits a signal if the user taps anywhere on the screen
+* other than itself. This signal is handled here.
+* Sub-chromes are hidden after a specified timeout if there is no user interaction with the
+* particular chrome. This class listens to the mouse events of the sub-chromes and
+* their children to manage this.
