Update README and CHANGELOG

CHANGELOG.md

 ## Recent Changes:
+- Ellipse parameters are now automatically calculated. You can still adjust them
+if you want, but the auto-calculation works exceptionally well.
+
+## Previous Changes
 - LOB Length is now determined by the distance to the furthest intersection from
 the receiver.
 - Fixed bug where map lags behind the receiver.
 - Changed the way ellipse and clustering parameters are handled. This allows for
 multi-user map interaction.
 - Updated to Cesium 1.79
-
-## Previous Changes
 - The LOB for each receiver on the map changes color based on the power and
   confidence thresholds.
     - Green when both power and confidence are above their thresholds

 - The smaller dots, if turned on vary in color from red to green. These dots are the individual
   intersections. The color represents the age relative to the full data set. Red is older, green is
   newer. This is very helpful for following moving targets.
+- LOBs can either be red, orange, or green.
