better loop for waiting for nodes in NodeThreadPool
better comments explaining what is going on in the NodeThreadPool
debugging pubsub with time
adding parameter and time nodes paused, now rename rxgraph to rqt
rxgraph renamed to rqt, TODO test this on ubuntu
timeMaster and timeIgnore almost done, TODO check if it works
	-small enhancements rqt vs rxgraph
	-added some classes under: simulator/src/java/main/ctu/nengoros/comm/rosutils/utilNode/
	-added new methods under RosUtils
fixed dependencies in the simulator-ui/nengo* scripts
seems that TimeMaster is started twice, check this..
timeMaster seems to work
time Masteer and time Slave work as expected, TODO some cleanup
TimeMaster works, IgnoreTime works, TimeSlave probably works, but axes in the simulator GUI are wrong (as expected)
paramHandler added, everything seems to work OK
removed loops from all Util nodes (not necessary)
adding nr-demo/time/ demos, now use MinMaxFloat, TODO: use TimeAwareNode
worning on nr-demo/basic/time*.py, TODO, now, in mode TimeMaster, launched TImeAwareNode will not start until interactive demo is launched and sends some data!
TimeMaster now periodically publishes 0 befor the simulation starts
now TimeMaster can restart publishing zer
time slave will not initialize all ROS nodes before data on /clock received
IgnoreTime node is also Ros Node now
added jrosparam to the nengo-cl script
