How to do DIRT-T fine tuning?

[mtngld]

Hi,

It is not clear to me how to use the DIRT-T solver,

The code has three DIRTTSolver:

1. salad/salad/solver/da/dirtt.py

   Line 110 in ba7abe1

   class DIRTTSolver(Solver):

2. salad/salad/solver/da/dirtt.py

   Line 148 in ba7abe1

   # class DIRTTSolver(Solver):

   (commented out, but uses KL which seems to match the paper)

3. salad/salad/solver/da/dirtt_re.py

   Line 36 in 190e350

   class DIRTTSolver(DABaseSolver):

Can you share an example of how to use it? And which one is the correct one?
