Adding the Django QuerySet tests and Converting the Data in level of object

* Creating the new project called ```testing```
  * Adding the Django QuerySet tests;
  * Adding Data parse Tests;
* Parse the data
  * if you have an `instance` of any Entity wich have a inheritance of HStoreModel, and assuming that you created a DynamicField to that Entity and he is called 'value', as an Integer, i built this manipulating the `to_python` method, inside the ModelField class:

```python
>>> DynamicField.objects.values()
[{
  'default_value': u'', 'name':  'value', 'order': None, 
  'max_length': None, 'typo': u'Integer', 'blank': True, 
  'choices': '', 'verbose_name': u'Value', 
  'id': 1, 'refer': u'Entity'
}]
>>> c = Entity.objects.all()[0]
>>> c.value
10
>>> type(c.value)
<type 'int'>
>>> c._dfields
{'value': '10'}
```
