2227,[Units] Missing partial specializations of the Boost.Lambda return type traits for dimensionless quantities,Torsten Maehne <Torsten.Maehne@…>,Matthias Schabel,"Hello,

I discovered some missing partial specializations of the Boost.Lambda return type traits for dimensionless quantities in the <boost/units/lambda.hpp> header, namely:

* quantity<dimensionless, X> + Y

* X + quantity<dimensionless, Y>

* quantity<dimensionless, X> - Y

* X - quantity<dimensionless, Y>

The attached patch adds the necessary specializations to the <boost/units/lambda.hpp> header and adds corresponding checks to <libs/units/test/test_lambda.cpp>.

Best regards,
