0847687fd1 don't create extra index on _types (fix #222) 
mongodb will use an index that begins with _types to service queries
against _types, so the extra index is only needed if no other fields are
indexed in the document. to be safe, we explicitly check all indexes to
see if any begins with _types, and only then prevent creation of the
additional index on _types.

5e7efcc8c2 Added 'hint' support, telling Mongo the proper index to use for the query. 
Judicious use of hints can greatly improve query performance. When doing a query
on multiple fields (at least one of which is indexed) pass the indexed field as
a hint to the query. Hinting will not do anything if the corresponding index
does not exist.  The last hint applied to this cursor takes precedence over all
others.

Current implementation is relatively simple, for complex schemas

4b9bacf731 Added ComplexBaseField 
* Handles the efficient lazy dereferencing of DBrefs.
* Handles complex nested values in ListFields and DictFields
* Allows for both strictly declared ListFields and DictFields where the embedded
value must be of a field type or no restrictions where the values can be a mix
of field types / values.
* Handles DBrefences of documents where allow_inheritance = False.

1126c85903 Added Custom Objects Managers 
Managers can now be directly declared in a Document eg::

```python
    class CustomQuerySetManager(QuerySetManager):

        @staticmethod
        def get_queryset(doc_cls, queryset):
            return queryset(is_published=True)

    class Post(Document):
        is_published = BooleanField(default=False)
        published = CustomQuerySetManager()
```

Refactored the name of the `_manager_func` to `get_queryset` to mark it as
part the public API.  If declaring a Manager with a get_queryset method, it
should be a staticmethod, that accepts the document_class and the queryset.

Note - you can still use decorators in fact in the example below,
we effectively do the same thing as the first example and is much less verbose.

```python

    class Post(Document):
        is_published = BooleanField(default=False)

        @queryset_manager
        def published(doc_cls, queryset):
            return queryset(is_published=True)
```

fc2aff342b Unique indexes are created before user declared indexes 
This ensures that indexes are created with the unique flag, if a user
declares the index, that would automatically be declared by the `unique_indexes`
logic.
