Class SequenceIndex

object --+
         |
        SequenceIndex

Stores indexes and provides quick access to mirrored sequences. Since we are not accessing the database directly, this provides a reasonably efficent alternative to doing a linear search through sequences every time when need one.

Iterating of a SequenceIndex instance will iterate over its sequences in order of id.
