Notes from LLNL development work

[jvita]

I will be using this issue to track comments/bugs that I encounter while working with ColabFit for the LLNL project. I will update this periodically as I go.

• [ ] database.insert_property_definition should have an overwrite=True option. I kept making mistakes in my property definition, then having to manually delete the old definition. Knowing how to manually delete a document may be difficult if you are unfamiliar with MongoDB.
• [ ] get_cleaned_property_instances() seems to assume that property definition names have the format <type>-<name> (link to corresponding line in code). While this lets things like potential-energy, atomic-forces, and cauchy-stress to load the fields energy, forces, and stress, it should not be a mandatory naming convention.

• [ ] it may be desirable for delete_dataset to optionally also delete the linked COs/DOs/PIs/... (only allowed if no other DS points to them)

• [ ] property insertion fails if "_metadata" is not provided. See this line.
