This class is the frontend class to Cocoa's text-manipulation architecture. For most purposes, programmers can use this class to interface with the text system; however, if more control is desired, than they may work with the individual component classes of the text system, which are NSTextStorage, NSTextContainer, NSLayoutManager, and this class. In terms of the Model-View-Controller pattern, NSTextStorage is the model, NSTextView is the view, and NSLayoutManager and NSTextContainer serve as controllers for the data layer and the view layer.
