Selects among three-mode principal component models of different complexities.

1	DimSelector(out, n, m, p, model)

`out`	Matrix with columns: number of components for the `A`-mode, number of components for the `B`-mode, number of components for the `C`-mode, goodness of fit (%), total number of components
`n`	Number of `A`-mode entities
`m`	Number of `B`-mode entities
`p`	Number of `C`-mode entities
`model`	Kind of model (1 for Candecomp/Parafac, 2 for Tucke3, 3 for Tucker2, 4 for Tucker1
