Contains a utility class {@link org.knime.core.node.config.Config} to store a general state (i.e. the user settings of all nodes, workflows, prediction models, etc.) in form of key-value pairs. The key is always a string, the value can be of type DataCell, DataType, RowKey and most of the generic types, and also another Config object in order to build hierarchical state structures.
All entries extend {@link org.knime.core.node.config.AbstractConfigEntry}, which provides a string representation of the value that can be serialized and written out as XML stream to file.
