Multi-layer and hex buildings

[DRG]

The original code as written has 8 types of buildings

0=GOVERNMENT
1=INDUSTRIAL
2=RESIDENTIAL
3=BUSINESS
4=OIL REFINERY
5=AIRFIELD
6=RADAR
7=SINGLE HEX

and there are four sets of code for the 7 MULTIPLE HEX BUILDINGS
one for type 0 , 4 , 5 and 6
one for type 1
one for type 2
and one for type 3

and there are subtle differences ( and randoms...there are always randoms ) in each set up for ground height. overall building height and density, as well, some use wood building code and others use "stone" building code

And the original SP2 code references "gpaved" 158 times ( SP3 only 115 times ) but in MBT it's referenced 274 times and in SPWW2 it's 284 times so this probably can be sorted out but it's not something glaringly obvious ATM so in the meantime if you place a multi then remove it make sure you clear every hex it had been on especially if you "dog pile" buildings and be aware that if the registration hex does not have a part of the building in it there will be a paved road showing so those would be best placed where you were going to have a paved road anyway
