	Following item from the To-do section of overview.html are now done:
	* Implemented commands to read and save files.
	* We ask for file and buffer names using a dialog pop-up window.
	* Split windows correctly, so that the windows that are not split
	keep their sizes, the windows being split gets split as specified,
	and the frame does not change size.  Now also handles horizonal splits.
	* Fairly good support for  buffer-local keymaps and Emacs-style keymap
	search order.  A new class BufferKeymap manages the active keymaps of
	a buffer.  Multi-key key-sequences are handled.  Pending prefix keys
	are remembered on a per-buffer basis (whereas Emacs does it globally).

	* Frame.java (addWindow):  Support horizontal splitting.
	(ask, toString):  New methods.
	* Window.java:  Now inherits from JTextPane.
	(wrap, getPanel, getWindow, delete, deleteOtherWindows):  New methods.

	makePointMarkerm getPointMarker, save, insertFile):  New methods.
	* BufferContent.java:  New class; extends GapContent.
	* Marker.java:  Partially re-write to use BufferContent features.
	(hashCode, equals, toString):  New methods.
	(insert):  New methods, moved from Buffer.java.

	* BufferKeymap.java:  New class; implements javax.swing.text.Keymap.
	* Keymap.java:  Removed;  defineKey methods moved to BufferKeymap.
	* InsertAction.java:  New class; extends javax.swing.text.TextAction.
	* FinalAction.java:  New class; extends javax.swing.text.TextAction.
