OnCloseTab

The OnCloseTab event can be implemented by a script add-in to receive notification when a tab is closed in a Lister.

Method Name:	OnCloseTab
Argument Type:	CloseTabData
Return Type:	bool
Description:	The CloseTabData.tab property identifies the tab that is closing. You can return True from this event to prevent the tab from closing, or False (which is the default) to allow it to close. Note that when a Lister closes this event is not triggered for each of its tabs - the OnCloseLister event provides notification when a Lister closes, and all the tabs in that Lister as discoverable through the CloseListerData.lister.tabs property.
