I am having trouble seeing how to use mixed units.
The program below compiles and runs.
See the changes I "wish" I could make as comments.

typedef quanttyus::foot_base_unit::unit_type Length;

Ok.  That makes Length represent "feet"
But I want Length to remain represented as an si::length, but input "ft" 
into it and convert to "ft" to print.

// static const si::length ft = ???;
typedef quantitysi::length Length;
Length x = 3.0 * ft;
cout << "x=" << convert_to_ft(x) << endl;
