Fix author information.

2000-05-04  Christopher James Lahey  <clahey@helixcode.com>

	* e-cell-text.c, e-cell-text.h: Fix author information.

	* e-table-group-leaf.c: Set a length threshold of 200.

	* e-table-item.c: Height cache is now actually a map.  Made
	"length_threshold" argument work.  If over the length threshold,
	use the height cache to get a better estimate so that once the
	height cache is full, height estimate is perfect.
