Subsets MSnSet instances to their common feature names.

1	commonFeatureNames(x, y)

`x`	An instance of class `MSnSet` or a `list` or `MSnSetList` with at least 2 `MSnSet` objects.
`y`	An instance of class `MSnSet`. Ignored if `x` is a `list`/`MSnSetList`.

An linkS4class{MSnSetList} composed of the input MSnSet containing only common features in the same order. The names of the output are either the names of the x and y input variables or the names of x if a list is provided.
