SharedPackedParseTree

interface SharedPackedParseTree

A Shared Packed Parse Forest is a collection of parse trees which share Nodes when possible. There is a Root Node. Each Node in a tree is either a Leaf or an Branch. An Branch contains a Set of Lists of child Nodes. Each list of child nodes is an alternative possible list of children for the Branch

A traditional ParseTree would be a special case (sub type) of an SharedPackedParseForest that contains only one tree.
