Detailed Description

SMARTS Parser.

This class implements the parser for SMARTS patterns. The SMARTS string is converted into a tree, which is used for matching it to molecules. The tree has also some additional features, i.e. additional edges which allows also for graph features (kind of cyclic structure).
