[Bldg-sim] TMY3 Released with 1020 US Locations

[Joe Huang]

As I mentioned in a previous BLDG-SIM post yesterday, you must change the 
station number from 6 numbers to 5 in both the INPUT.TMP file and the first 
header line of the TMY3/TMY2, i.e., WEATHR.TMP, file. If you don't, you will
either get a warning that the station number in the INPUT.TMP is too big, or 
another one that the station number doesn't exist on the WEATHR.TMP file.
