deepsearch 0.1

deepsearch is a Haystack extension used to index deep and nested model relationships. Its key features are:

• deepsearch.indexes.DeepSearchIndex class able to index deeply nested related objects and their fields.
• deepsearch.models.FieldBoost model that stores weights of each index field for query-time field boosting.
• resume_index command able to reindex a slice of all objects or only a subset of index fields.
• Celery support for real-time indexing.
