27 FUNCTIONAL DESCRIPTION
28 ------------------------------------------------------------------------------
29 Initialice the FGPhysicalProperties struct to something sensible(?)
32 ------------------------------------------------------------------------------
33 29.05.1999 Christian Mayer Created
34 16.06.1999 Durk Talsma Portability for Linux
35 20.06.1999 Christian Mayer added lots of consts
36 11.10.1999 Christian Mayer changed set<> to map<> on Bernie Bright's
38 19.10.1999 Christian Mayer change to use PLIB's sg instead of Point[2/3]D
39 and lots of wee code cleaning
