Heat-pipe connected entities?

[piecat]

Hi,

I'm somewhat new to modding, but today I decided I'm going to make one.

I need to be able to find the connections/neighbors of a heat pipe. I spent most of today trying to figure this out, but as far as I can tell, heat-pipes don't have a property that references their neighbors, unlike every other connectable item (belts, pipes, etc).

The 'heat_buffer_prototype' does have a property called connections, but this appears to be an array of arrays which contain a position vector (all are 0,0 for all heat-pipes I placed), and a direction (1=north,2=east,etc)

If I'm not mistaken and this doesn't exist yet, could this be added please?
