PORTAL FINDING ALGORITH
=======================
- -Get clicked base block
- -Trace upwards to find first obsidian block; aborts if anything other than obsidian or air is encountered.
- Uses this value as a reference (the 'ceiling')
- -For both directions (if one fails, try the other), BASE (clicked) block:
- -Go in one direction, only stop if a non obsidian block is encountered (abort) OR a portal border is encountered (FindObsidianCeiling returns -1)
- -If a border was encountered, go the other direction and repeat above
- -Write borders to XZP and XZM, write direction portal faces to Dir
- -Loop through boundary variables, and fill with portal blocks based on Dir with meta from Dir
