Graphics: Followed canvas API changes.
Radio: Renamed computeMin to getMin.
Radio: Added error rates to reception indication.
Radio: Fixed running multiple runs in the same simulation.
Radio: Simplified scalar names.
Radio: Moved radioChannelChanged signal to Ieee80211Radio.
Radio: Added error rate signals.
Example: Added example that shows how PER, SNIR, and distance relates to each other.
Radio: Finalized the IEEE 802.11 error model.

The old error model still used dblrand, the new one is purely functional.
Updated fingerprints.
Radio: Renamed variables for easier understanding.
Radio: Revived error rate indications.
