Hello @thvasilo , I was unable to access the `create...` functions from the
scala API. I'm not sure how to pass a `DataSet[Double]` to a
`DataSet[java.lang.Double]` function. I am using the following right now:
```scala
class DoubleDataSetUtils(val self: DataSet[Double]) {
def createDiscreteHistogram: DataSet[DiscreteHistogram] = {
wrap(jutils.DataSetUtils.createDiscreteHistogram(self.javaSet))
}
}
implicit def utilsToDoubleDataSet(dataSet: DataSet[Double]) = new
DoubleDataSetUtils(dataSet)
```
I'm not terribly familiar with the `TypeInformation` and `ClassTag`
mechanisms.
As for docs, where should I put them? Currently, the java docs for the
class themselves are written properly. However, there is a file named
`zip_elements_guide.md` under `apis` folder. Should I rename that instead to
`Data Set Utilities` and add histogram docs there itself?
