[x3d-public] TimeSensor Control

[Joe D Williams]

<TimeSensor DEF='GBTimer' cycleInterval='100' loop='false' enabled='false' />

<BooleanSequencer DEF='GBTimerControl' 
key='0 1'
keyValue='true false' />

<ROUTE fromField='fraction_changed' fromNode='GBTimer' toField='set_fraction' toNode='GBTimerControl'/>
<ROUTE fromField='value_changed' fromNode='GBTimerControl' toField='enabled' toNode='GBTimer'/>

What combination of parameters so I need to get this to just Run Once then stop.
Seems like if I start with loop='false' it doesn't go. 
enabled true or false sent by control does nothing 

Thanks, 
Joe
