Array slicing. Specify lower and upper indexes to slice an array.

[ABridoux]

Let the user specify a lower and upper bounds of the elements to display.
Possible syntax: array[lower:upper], array[lower:] to target all indexes from min and array[:upper] to target all index up to max, and array[:] to target all the elements in the array. The CRUD subcommand could then be applied. The read subcommand should output a list.

Examples

Given the following JSON

{
  "names": [
    "Thomas",
    "Jim",
    "Enzo",
    "Duke"
  ],
  "devices": [
    {
      "Id": "ABC",
      "Registered": true
    },
    {
      "Id": "123",
      "Registered": false
    },
    {
      "Id": "456",
      "Registered": false
    }
  ]
}

scout names[1:2] should output Jim\nEnzo
scout delete names[1:]should delete the names Jim, Enzo and Duke
