OK, commited. The D2 parameter has disappeared. It is now replace in the 
message by a power parameter that describe the power applied to the 
distance difference :

old "K(L[n] - L[0])" becames "K(L[n] - L[0])^p

It means that with L[0] = 0 and p = -2, you can make gravity field...

Oriented links has been implemented, you can now project forces onto 
lines or planes...

...and help files are made according to the template n°4 from Ben 
Bogart, with many infos in the "more_infos" subpatch and a few 
differences dues to the great number of messages.

Cheers,

Nicolas
