Importing non-numeric properties from halo finder about tangos

[apontzen]

The actual mechanism by which things are stored in the database is all here:

https://github.com/pynbody/tangos/blob/master/tangos/core/data_attribute_mapper.py

Currently there aren't any mechanisms for strings or booleans. Of course a boolean could be stored as an int...

I don't think there is a particular reason that numpy arrays are ignored. It's probably an oversight, and an extra condition should be added.

I see. I'm happy to add a further test to include numerical numpy arrays.

As a curiosity, is the rest of Tangos forbidding non-numerical properties? I don't think I ever tried, but I couldn't store a boolean, or a string in the database?
