All functions of the Convert class take a unique pointer to a pattern. You can
specify your own pattern, and use that in the conversion. The code is all in
deal.II/base/patterns_tools.h
After the Class declarations, you’ll find the implementations for the basic
classes of deal.II, including vector, map, pairs and tuples of them.
