Detailed Description
Class for the passive projection tree.The passive projection tree is kept up to avoid the interleaving of path steps that have been optimized away. Basically, each node represents a single path step, and each path from the root describes a complete path. Nodes matched on this path during preprojection must not be interleaved.
