david d4c49d65ac Major weather update from Christian Mayer, tying the weather code into
the property system, among other things.  A separate integration into
the FDMs will follow shortly.

This code will be used only if the --with-new-environment option is
*not* passed to configure.

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