A Random data stream that generated data points that are clustered in several subspaces.

`numAtts`	the number of dimensions of the data stream.
`numCluster`	the average number of clusters at any point in time.
`numClusterRange`	amount by which the actual number of clusters can deviate from numCluster.
`avgSubspaceSize`	the average number of dimensions in the subspace of a cluster.
`avgSubspaceSizeRange`	the amount by which the number of dimensions can deviate from avgSubspaceSize.
`kernelRadii`	the average radii of the clusters in the model.
`kernelRadiiRange`	the amount by which the radii can deviate from kernelRadii.
`numOverlappedCluster`	the number of overlapped clusters at the beginning of the stream.
`overlappingDegree`	how close the initially overlapped clusters are
`densityRange`	how strongly the amount of points in each cluster differs from each other. 0 means all clusters have the same size. 1 is the maximum value.
`noiseLevel`	amount of noise
`noiseInCluster`	can noise be placed in a cluster?
`speed`	every speed points, the clusters move by 0.01
`speedRange`	speed/Velocity point offset
`eventFrequency`	events happen every eventFrequency points if at least one event is enabled and numClusterRange is set
`eventMergeSplit`	can clusters merge or split?
`eventDeleteCreate`	can clusters be deleted or created?
`subspaceEventFrequency`	Subspace event frequency by each cluster movement destination.
`decayHorizon`	decay horizon
`decayThreshold`	decay horizon threshold
`modelRandomSeed`	number used to seed the RNG for the model
`instanceRandomSeed`	number used to seed the RNG for the instances
