DSC_ThreeStage: Construct Subspace Stream Clusterers
In subspaceMOA: Interface to 'subspaceMOA'

This function allows you to combine a micro clustering algorithm and a macro clustering algorithm into a single object that can then be used as a normal DSC object. This object can then be used with e.g. update to produce a micro clustering of a stream.

1	DSC_ThreeStage(macro, micro)

`macro`	a dsc object representing a macroclustering
`micro`	a dsc object representing a micro clustering, which can be obtained by calling e.g. DSC_subspaceCluStream.

The microclustering component is implemented as usual, i.e. a DSC_ThreeStage object with a DSC_subspaceCluStream microclustering component will produce the same microclusters that a normal CluStream would have produced. This is the first of the three stages.

Whenever a macro clustering is requested, Multivariate Gaussian Distributions around the positions of the microclusters are used to simulate the original stream. This is the second stage.

Then the macro clustering is performed on the points generated by these distributions using the selected macro clustering algorithm. This is the third stage.

Possible choices for the micro clusterer are DSC_subspaceDenStream and DSC_subspaceCluStream. Possible macro clusterers are DSC_clique, DSC_p3c, DSC_proclus and DSC_subclu. Other clusterers are currently not supported.
