Splitter

A Splitter is the placeholder name given to a structure seen in the E3 trailer. It is shown to take items from a single input belt, outputting them between three other belts. Splitters can also sort items between their outputs.

Types
There are three known types of splitter, each with different sorting capabilities. It is unknown if they are separate buildings, upgrades, or settings.

"Basic"
The standard splitter appears to simply split items between its outputs in sequence.

"Sorter"
Unknown, but seems to send a specified item out its side outputs, sending all others out its forward input.

"Multi Sorter"
Also unknown, but theorized to function as the "sorter", but allowing for lists of items to each output.
