+
+	[sdf] Temporary change.
+
+	Added new property to dynamically change the
+	optimization to be used to generate the SDF.
+	This can be used to compare the performance of
+	different optimization techniques without going
+	and recompiling the program.
+	And will also be used in the demo to check the
+	performance.

 	[sdf] Added more properties.
