### Some ideas of what this could look like

```bash
  $ automege export foo.mpl
  {
     "name": "bob",
     "numbers": [ 1,2,3,4 ]
  }
  $ automerge export --format toml foo.mpl
  name = "bob"
  numbers = [
    1.0,
    2.0,
    3.0,
    4.0
  ]
  $ automerge import foo.json --out bar.mpl
  $ automerge export foo.mpl | automerge import - > bar.mpl
  $ automerge set foo.mpl "birds[3].name" "wren"
  $ cat wren.json | automerge set foo.mpl "birds[3]"
  $ automerge get foo.mpl "birds[3].name"
  $ automerge union foo.mpl bar.mpl --out baz.mpl
  $ automerge intersect foo.mpl bar.mpl --out baz.mpl
  $ automerge union foo.mpl bar.mpl - > baz.mpl
  $ cat foo.mpl bar.mpl | automerge union --out baz.mpl
  $ cat foo.mpl bar.mpl | automerge union - > baz.mpl
  $ automerge status foo.mpl
