[PSUBS-MAILIST] Spherical Shell Calculator

[Jon Wallace via Personal_Submersibles]

I've put links up on the web site:  WWW.PSUBS.ORG -> Resources & 
Reference -> Design Tools -> Calculators & Datasheets -> Pressure Hull 
-> Shell Calculator Software (Windows 64 bit)

The Runtime Engine took a few minutes to download and a few more to 
install.  You have to reboot your computer for it to take effect (I 
haven't rebooted yet).
