Quantitative preservation mode

[1000i100]

I would like to make monetary system simulation.
For this use-case, in most case i would like to preserve the amount between inbound and outbound.

What about a node behavior where :

1. what enter is stored a little time to aggregate multiple input value
2. the output value is equally divided between each output arrow

so node could have a switch in config with 2 modes :
signal cloning mode (default) || value preservation mode
and a scale [ 0, 0.1, 0.5, 1, 5 ] seconds of retention time to aggregate signal. (or other value in the scale)

TODO : signal cloning mode (default) || value preservation mode

I will handle this by edge and not by node :
if no quantitative edge take the signal out, the signal amount is added to the node (like now), if some quantitative edge take the signal out, the signal amount is splitted between edge and not added to the node (or partialy depending on threshold)
