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.
