Certain k/v db's such as LevelDB do not have the idea of buckets.

A 'collection' could be anything that implements a simple interface for operations. From here drivers can be created for common dbs (bolt would use a bucket to satisfy the interface). If someone is unhappy with a drivers implementation, they can implement their own.

Method to return buckets of a db

A cursor implementation is needed.

Rumble should provide full sub-bucket support.

Potentially look in to treating values that are maps / structs as a sub-bucket by default depending on how boltdb handles this (see boltdb/bolt#473).

New method for Iter that sets the pipeline to a channel of interface. This method will be used if the value needs to be unmarshaled to determine if it should be part of the pipeline (eg. filtering). DB.Unmarshal will not be called on the interface given to the pipeline, but SetId will be called.

Return a new error type "KeyNotPresentError" or similar

Convert Put(v interface{}) to Put(v interface{}...)

Put should batch the transaction to a given size. See boltdb/bolt@e334569 and boltdb/bolt@adbb1a1

Unsure if Db.Batch should be the default.
