importance added to the demos cripts
nr-demo/sarsa.py improved comment
created new prosperity measure: reward/step+forgetting binary coverage: each step the agent forgets a random state
logPeriod (by default 100 added to all scripts)
conclusion: this works flawlessly over the ROS network, but terribly in the Nengo, TODO: why?
qlearn and mapII work very well, TODO: add n-step action buffering (memory for past actions)
