ExtractFeatureGroups retrieves groups of features (types with their different values) from a given set of FeaturesMaps.

LoadAndParseFeatureJSON loads the features from a JSON file at a given path and parses the content into a list of FeaturesMap.

ParseFeaturesJSON parses features from a JSON schema into a list of FeatureMaps.

A FeaturesMap maps feature types to values, defining a token.
