Added update of samples in a project from a CSV file

For Uppsala. No test written yet, I had no time. Will do so next week.
I just found [this design pattern](http://code.activestate.com/recipes/66531/) by Alex Martelli today which I thought was neat that kind of persists a dictionary between calls:

```python
class Borg:
    __shared_state = {}
    def __init__(self):
        self.__dict__ = self.__shared_state
```
Sort of like a "Singleton," with the difference that you create multiple instances all of which share the same state.
