+	I have finished the basic implementation of the update mode.
+	I have been able to demonstrate substantial improvements in
+	speed when the number of existing measurements dominates the
+	total number of measurements and the number of averages is
+	typically small compared to the number of measurements (ie,
+	most objects are real, detected in most images, and each new
+	image supplies many new measurements of objects which exist
+	and not many of objects which don't exist already).  The speed
+	gain is significant in this context because the average table
+	is small compared to the measure table; since both update and
+	full-load methods require the complete average table, there is
+	no difference in the load time for the average table.  
+
+	I was having some memory collision problems, and attempting to
+	use the ohana_allocate functions reminded me that the libFITS
+	functions were not supported under ohana_allocate.  This was
+	unhelpful.  I bit the bullet and split libohana into libohana
+	(base functions only, including ohana_allocate) and libdvo
+	(functions based on the libautocode structures).  Doing this
+	allowed me to make libFITS depend on libohana (including
+	ohana_allocate).  BUT, this forced me to change all LDFLAGS
+	entries in ohana to swap -lohana -lFITS for -lFITS -lohana,
+	and to add include <fitsio.h> in some cases.
