Table of behavior sessions and models

[alexpiet]

Is your feature request related to a problem? Please describe. Behavioral sessions will have behavioral models fit to them. These models will be separate data assets from the NWB files. We need:

• [ ] A way to find what models have been fit. We could query by session: "find all models fit to this session", or we could query by model " find all sessions this model has been fit to". Both are probably valuable
• [ ] A way to load the model results. The model results should be in the same format as the "trials table", and can easily be merged onto the trials table. The additional columns will depend on the model but should have the naming scheme of "_". Column names might include Q values or other latent variables, choice prediction, or goodness of fit metrics.
