(#8010) Add getvar() rvalue function
This isn't directly related to #8010, but rather indirectly fills the
need to allow the end user to configure where data values are looked up.
This allows the namespace to be passed as a class parameter. A module
may then quickly and easily look up data from the user-defined
namespace.
