TABLE
	(Mostly done)
	New table format. It uses csv files.

	If a cell contains _, it means it is merged with the preceding one.
	This ia a simple syntax to express multi-cell. To have more control, we
	could use the following _L _R _U _D. _ is like _L. It means that
	we merge this cell with the one on the left, _R, with th next one,
	_U, with the one on top, _D, with the one below. We probably
	only need _U and _.

	For table, we could have the special sequence control #N. This means
	the cell has to be highlited when we display step N of the table
	like the bulle item.

	We need a simple way to express there is a heading and row title.
	A Line starting with & could carry formatting directives

COMMENTS
	(Done)

	Comments are expressed with # ...
	They could be expressed by

	##
	some comments
	another line
	##

	A little like C, but simpler to write.

	Comments could be presented in a note pan during presentation.

CHARTS

	We need a way to create bar chart quickly, again with highlit
	and show mode.

LIBRARY

	We need to create a library to read the various formats (items, table, graph)
	so we can easily parse that in the sequence utility to tell how many steps
	are available in one slide.

-----

In the preview/control screen, we use highlit to present items, but --show on
the main screen. So the presenter can see all the items.

-----

Possibility to edit a slide using the web interface

Powered by nocracks at the bottom right of an empty page.

-----

Empty html page (written empty in the center) used by the sequence
engine to show the start and the end of the slide show.
