+- Removed saccades algorithm to provide more comprehensive scanning. This will allow SNF to
+operate as a feature extractor for machine learning algorithms by matching "above-band" rules
+that do not compete with normal "in-band" rules.
+
+The growing use of above-band rule groups like "Experimental Bulk/Noisy" and additional groups
+for machine learning feature extraction has changed the paradigm for heuristic competition in
+the SNF world. Where previously it was important to optimize scanning performance for low-powered
+hardware and heuristic competition could add pressure to select for more efficient rules; the
+new paradigm requires that any available patterns will match (at least once) and hardware
+constraints are no longer a serious concernt. For example, SNF is easily able to operate at
+scanning rates that are 3 orders of magnitude higher than most deployments require on modern
+equipment.
+
+This isn't to say that heuristic efficiency optimization will be going away -- but rather that
+the mechanisms for optimizing that efficiecncy can be moved more toward the back-end so that
+the front-end scanners can concentrate on making all available matches available for analysis
+and even more sophisticated learning algorithms.
+
+Saccades was fun, and effective, but it's time has passed.
