//	CHNotebookTextContainer implements a general algorithm for wrapping
//	text around rectangular media embedded in an NSTextView, a capability
//	not supported by the native text system. The class accomplishes this
//	by overriding the lineFragmentRectForProposedRect:sweepDirection:
//		movementDirection:remainingRect: method.

//	The algorithm takes into account any number of rectangular holes in the
//	container geometry in any configuration along both the x and y axis.

//	This class handles only the geometry of the text container in isolation
//	from a number of other important UI functionality, such as placement of
//	media and drag and drop. A complete page layout system will likely
//	incorporate custom NSLayoutManager and NSTextView classes.

//	For more information refer to the NSTextContainer, Text System Overview,
//	and the Text System Storage Layer Overview documentation
