> if a uniqueKey field is defined, then the IndexSchema should fail fast & hard 
> on startup if the field type of the specific uniqueKey uses "points" (ie: 
> {{FieldType.isPointField()}})
> The reason for this is because deleting by id, and overwriting existing 
> documents are predicated on being able to use 
> {{IndexWriter.deleteDocuments(Term...)}} and 
> {{IndexWriter.updateDocument(Term, Iterable<..docs..>)}} respectively -- but 
> Points based fields have no "Term" that can be based to these methods.
> IndexSchema.readSchema should fail fast in this case with a clear error (just 
> like it does if the uniqueKey field is multivalued)
