Function: The class for the text storage of a text view.
NSTextStorage is a semiconcrete subclass of NSMutableAttributedString that manages a set of client NSLayoutManager objects, notifying them of any changes to its characters or attributes so that they can relay and redisplay the text as needed. NSTextStorage defines the fundamental storage mechanism of the Application Kit's extended text-handling system.

NSTextStorage also defines a set of methods, listed under "Getting and setting scriptable properties" in the Method Types section, useful for getting and setting scriptable properties of NSTextStorage objects. Unless you are dealing with scriptability, you do not normally need to invoke these methods directly. In particular, using the characters, words or paragraphs methods or their corresponding setter methods is an inefficient way to manipulate the text storage, since these methods create and return many objects. Instead, use the text access methods defined by NSMutableAttributedString, NSAttributedString, NSMutableString, and NSString to perform character-level manipulation.
