[ndnSIM] N consumers M distinct producers

[Josh J]

Tracing thru gdb I find the following error being throw. Though no idea
what it means? What required marker is necessary?

    {
      BOOST_THROW_EXCEPTION (error::name::Component ()
                             << error::msg ("Name component does not have
required marker [" + toUri () + "]"));
    }
