 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,

 Torsten Maehne
