Add FeatureSet class that holds List of features and the fieldDefinitions object
requested to merge transformer-spring-refactor-query-entity-fix-lr into transformer-spring-refactor-pad
- Fixes bug where features with fields of varying types were not saved consistently
- Now a FeatureSet contains a single fieldDefinitions property that applies to all encompassed features
Philip, let me know what you think of these changes. I've tested and have successfully run Koop against the Ignite Cache served up with this code.
