UnitsSameCluster enables to control the labels of the clusters which contain predefined units

```
```

Start with labelling produced by tclustIC and produce consistent labels.`IDXwithConsistentLabels`

=UnitsSameCluster(`IDX`

,
`UnitsSameGroup`

)

```

Example with detailed description of output element OldAndNewIndexes.`IDXwithConsistentLabels`

,
` OldAndNewIndexes`
