PK - Added Jacobson/Karels Algorithm RTT estimation to adapter code. It furnishes an established idea of current RTT for use by schedulers. Jacobson/Karels Algorithm specification doesn't discuss adding to estimated timeout any effect of actual timeouts. So, I added a penalty to the estimated timeout if an actual timeout occurs (added 0.1 seconds to estimated timeout). Temporarily, I connected the suggested timeout value to the actual timeout value and it worked VERY well. | PK - Added Jacobson/Karels Algorithm RTT estimation to adapter code.

+ | PK - Later. Improved GUI graphing. Realized there was no way to zero bins for seconds in which no segments were sent. New code has additional benefit of scrolling in new data. |
