Find the intersection of two collections of objects

```
intersect(x, y, ...)
# S3 method for default
intersect(x, y, ...)
# S3 method for neuronlist
intersect(x, y, ...)
```

## Arguments

- x
the first collection to consider.

- y
the second collection to consider.

- ...
additional arguments passed to methods

## Value

A collection of the same mode as `x`

that contains all elements
of `x`

that are also present in `y`

.

## Details

Note that intersect.default calls base::intersect to ensure
consistent behaviour for regular vectors.
