   requires store update

   The update now updates into a seperate directory.

   use the new transactions of the recordstore which may nest.

   added the following methods to the Data::ObjectStore :
    * lock( @locknames ) - uses flock to lock those lock names
    * unlock - unlocks all locks this store has locked

   added the following methods to the Data::ObjectStore::Container :
    * vol( key, value ) - gets/sets a keyed volatile value which is not saved
    * lock( @locknames ) - uses flock to lock those lock names. convenience, just calls the store's method
    * unlock - unlocks all locks this store has locked. convenience, just calls the store's method
    
   added a METADATA field to the objects which contains
    * created time
    * updated time
    * connections - number of connections this has to the root
    * backconnections - { id => count } of items connected to this
   the class plus the metadata fields are joined by | and ended by a
   space. Together, they make the head descriptor of the object.

   big arrays and hashes
