26 FUNCTIONAL DESCRIPTION
27 ------------------------------------------------------------------------------
28 wind item that gets stored in the micro weather class
31 ------------------------------------------------------------------------------
32 28.05.1999 Christian Mayer Created
33 16.06.1999 Durk Talsma Portability for Linux
34 20.06.1999 Christian Mayer added lots of consts
35 11.10.1999 Christian Mayer changed set<> to map<> on Bernie Bright's
37 19.10.1999 Christian Mayer change to use PLIB's sg instead of Point[2/3]D
38 and lots of wee code cleaning
39 21.12.1999 Christian Mayer Added a fix for compatibility to gcc 2.8 which
40 suggested by Oliver Delise
