fromString

public static Granularity fromString(String str)

mergeGranularities

public static Granularity mergeGranularities(List<Granularity> toMerge)

simple merge strategy on query granularity that checks if all are equal or else returns null. this can be improved in future but is good enough for most use-cases.
