Fix multiple const ref parameters on objects

If a class method had more than one const parameter by reference, then the code generation had no matching template. Fixed by filling in the template code expansions for N const reference parameters.

Add "usage()" parameter to def()

Allow usage("command arg arg...") parameter in policy argument to def().
