MultiTag intersection object

It came up in a discussion that intersecting MultiTags might be a useful feature. This could be a method that takes a list of MultiTags (or their names) and returns a new type (MultiTagView? similar to how a DataView is a sliced view of a DataArray) that has positions and extents that represent the intersection of the provided MTs. Similarly, the references of this MultiTagView would be the DataArrays that are referred to by all provided MultiTags.
