Create Transport Line Backbone

[Tarig0]

Will be creating the following.

1. Pylon block
2. Pylon ItemStack (store last pylon pos)
3. Pylon Render (Something Fancy) (optional)
4. Render for Tethers (ropes at first)
5. Pylon TileEntity

[Tarig0]

Usage will be.

Craft Stack of Pylons

Place Pylon

if (stack.prevpos != null) {
  PylonEntity parentTile = GetTileEntity(stack.prevpos, PylonEntity)
   if (parentTile != null && parentTile.ValidChildPos(CurPos)) {
      parentTile.setChild(curPos)
      CurrentTile.setParent(stack.prevPos)
   }
}
if (stack.qty > 0) {
 stack.precpos = CurPos
}

[Tarig0]

new stack will be bound to a pylon by right clicking that stack on a pylon that does not have a child

[Tarig0]

Tether rendering will be handled by parent pylon

[Tarig0]

Added rule can not force a binding between a pylon with children to a new parent,

possible to allow for cascade unbind, or cascade re-bind, but won't be implemented at first

[Tarig0]

Shift right click with stack will create a sibling of the current prevpos
