This OverNode is used to implement a countdown functionality.
This is a Flow OverNode, in which the flow is forked into two separate branches, represented by two output flow ports. A Seconds numeric value needs to be provided representing the ammount of time needs to pass in order to proceed.
The On Time Still Remaining branch directs the execution flow to a sub-part of the Graph as long as the Time Remaining value is greater than 0.
