Changed the HorizontalDataResolutions element to HorizontalDataResolution and added sub element objects to aid in more clearer error messages when users make schema mistakes. Before the JSON schema validator spewed a lot of misleading error messages making it hard to figure out what the user did wrong.

Added a description for AdditionalAttributes/Name so that the help text shows up in MMT.

• Changed the order of elements, the UMM-C definition comes first then followed by the class definitions.  The umm-c-json-schema_v1.13_order_change.json file was created to show the changes from v1.13 to include only the element order changes.
• Moved TilingIdentificationSystem and SpatialExtent from umm-cmn to umm-c. The umm-c-json-schema_v1.13_order_changed_combined.json file was created to show the changes moving the TilingIdentificationSystem and SpatialExtent and of their child classes from umm-cmn to umm-c. The TilingIdentificationSystem, the SpatialExtent, and their classes were all removed from umm-cmn-json-schema.json file.
• Removed IdType from umm-cmn-json-schema.json because it was not referenced anywhere.
• Starting from the umm-c-json-schema_v1.13_order_changed_combined.json file the following changes were made to produce the umm-c-json-schema.json file:

    1) Removed the HorizontalCoordinateSystem element from SpatialInformationType class

    2) Added the ResolutionAndCoordinateSystem element with the ResolutionAndCoordinateSystemType definition to the HorizontalSpatialDomainType class.

    3) Renamed HorizontalCoordinateSystemType class to ResolutionAndCoordinateSystemType.

    4) Added the description element to the ResolutionAndCoordinateSystemType class

    5) Removed the GeographicCoordinateSystem element and its class (GeographicCoordinateSystemType)

    6) Added HorizontalDataResolutions element with the HorizontalDataResolutionType definition to the ResolutionAndCoordinateSystemType class and allowing multiple instances of this class.

    7) The new HorizontalDataResolutionType class contains 7 choices with up to 8 new elements.
