Hey! So there’s some refactoring to move the sqlmodel and errdapmodel into an interface subfolder, this is because they are both more of a translator than a model for data.

I also included the sql schemas that Jim made, I refactored the ooi_ui_schema a bit to support how the ui needs to search on the data.

The tests are also slightly updated, I was trying to consolodate some redundancies but it got away from me…so I just put it back to when it was working.

I also updated the README.md file.
