There are native version of writeMPS() and writeLP(), which asks for
variable names and  constraint names as input parameters. Not sure why this
is needed if  methods setRowName(), and setColName() are provided.

It might be possible to query the variable index of the osi model, and then
create the var names with correct index as input parameter to the native
version of writeMPS() and writeLP(). But I didn't try.
