Abstract Model Repository

[Jennifer]

I have been having issues creating an Abstract Model Repository as I will need that to load models from BioModels.

I follow the code in  abstract_model_repository.py and without fail, I get ImportError: attempted relative import with no known parent package. 

how do I fix this, please?

Hmm could be your local development setup. But biomodels is already supported as a model repository. So it should work out of the box. For instance:

```

from cobra.io import load_model

mod = load_model("BIOMD0000001062")

```
