Hi Feng,

thanks for advice. The work to remove all those
lines is the minimal. But the code will not compile,
if you do not change corresponding methods/class names.

https://github.com/yade/trunk/commit/697f1078b37c9803ce314441e6965227404b9dd8
https://github.com/yade/trunk/commit/8ddf512a66a7c4bbd608abfbf7e1ea7a5b1882de

It is completely fixed now. I just ask not to use this
construction for a new developing code.

Have a nice weekend

Anton
