I had a need for tree surrogates with multiple outputs and OMLT did not support them. I have updated the LMDT definition and formulations to enable this. I have added some tests for this feature as well.
This should be better than using multiple different trees on the same input space for different targets/outputs.
It is compatible with the linear-tree package and the systems2atoms hyperplane trees that I have also been working on.
Addresses issue #161 which is a request for this feature!
