Isabelle

added functor Linear_Set, based on former adhoc structures in document.ML;
Linear_Set.delete_after (ML): actually delete table entries;
Scala Linear_Set: clarified exceptions, according to ML version;
simplified Document.node using Linear_Set;
ML Document.edit: refer to start via NONE instead of no_id, according to Scala version;
