> In code RawMeasureType#RawMeasureType, we can see that both funcName and  
> dataType are use, and this can be remove cuz there's no constraint on its 
> constructor.
> {code:java}
>     @SuppressWarnings("unused")
>     private final DataType dataType;
>     public RawMeasureType(String funcName, DataType dataType) {
>         this.dataType = dataType;
>     }
> {code}
> And after we done that, we can more easily test MeasureType without passing 
> in meaningless args(AggregatorMemEstimateTest#112).
> Like codes in org.apache.kylin.measure.dim.DimCountDistinctMeasureType, other 
> implementations can be cleaner.
