Soc2014 meta unittests

Contains:
- unit tests for current implementation of Options
- renamed to models_meta to avoid name clashes
for the end of a list, I prefer this style:
```
    'object_id_concrete',
]
```
This has the advantage of not needing to modify a line like `'object_id_concrete'],` when adding more items to list which keeps subsequent diffs and git blame cleaner.
