Bridge Builder

This attachment module lets the cart build a bridge where it can't put rails with a Railer.

Interface
When the cart reaches the end of a track it will look to see if there is a block where a track should go, if there isn't, it will place a block.
 * This module wouldn't make much sense to use without any railer.
 * This module works well with a Height Controller and is also a good addition when using a drill.

There are 3 slots in the cart that are under the "Bridge" title where you can put blocks it will use. The slots only accept a certain number of blocks to build with. The blocks it accepts are:
 * Stone
 * Planks
 * Brick
 * Stone Brick
