Examples of FeatureDefinition

org.vocvark.DataTypes.FeatureDefinition
Objects of this class each hold meta-data about a feature, as specified by the five public fields. Objects of this class do not hold any feature values of particular instances.
Methods are available for viewing the features, veryifying the uniqueness of their names, saving them to disk and loading the, from disk.
