Conveyor Splitter

A Conveyor Splitter is a building that takes items from a single input Belt and outputs them between three other belts. If an output belt is not fast enough and gets stuffed, and if any filter applied allows it, the items on the input belt will be divided equally between all others non stuffed output belts. If all output belts are blocked, the items at the input belt will have to wait.

Types
There are three types of splitters available, each with different sorting capabilities.

"Basic"
The standard splitter appears to simply split items between its outputs in sequence. If any output is full, it will distribute the incoming items into the remaining outputs evenly.

"Smart"
Splitter with 3 outputs. Each output can have a filter set to either "none", "any" or one specific item type.

"Programmable"
Splitter with 3 outputs. Each output can have multiple filters.

Trivia
It is easy to differentiate between input slot and output slot by looking at the shape of LED light at the belt connector. The output is indicated by a arrow-like light, while the input is 3 smaller dotted light.
