Bio::LiveSeq::ChainI - Double linked chain data structure


  #documentation needed


This class generates and manipulates generic double linked list, chain, that can be used to manage biological sequences.

The advantages over strings or plain arrays is the ease of tracking changes (mutations) in the elements (sequence). The other side of the coin is that these structures need consideraly more memory, but that is cheap and constantly inceasing resource in computers.
