The aggregate operation to obtain the total calories of the food in kilocalories.

This helps to create an AggregateRequest instance to get the total calories of the food simply and easily.

This aggregate operation allows the application to set the following:

• A time filter with LocalTimeFilter or InstantTimeFilter.

• A time filter using LocalTimeFilter along with grouping by LocalTimeGroup, or
  a time filter using InstantTimeFilter along with grouping by InstantTimeGroup.

• The data's source filter with AggregateSourceFilter.
  AggregateSourceFilter.fromPlatform means obtaining data generated by the Samsung Health.

• A data order with Ordering.

// set a Local date time range from midnight to now
val startOfDay = LocalDate.now().atStartOfDay()
val now = LocalDateDate.now()

val aggregateRequest = DataType.Nutrition.TOTAL_CALORIES.requestBuilder
    .setLocalTimeFilter(localTimeFilter)
    ... // set some filters or conditions
    .build()
