Splitter

A Splitter is a structure that splits resource between multiple conveyor belts. It has been seen in the E3 trailer and the conveyor belt gameplay video. 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 simply splits 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.
