 Parameters defining the search used to solve vehicle routing problems.

 If a parameter is unset (or, equivalently, set to its default value),
 then the routing library will pick its preferred value for that parameter
 automatically: this should be the case for most parameters.
 To see those "default" parameters, call GetDefaultRoutingSearchParameters().
