CLI and supported JsonPaths

[ainthek]

What syntax can be used to access arrays ?
I believe that this is correct JSONPath, but it does not work from CLI.
Please provide more info in readme.md if possible

cat sample.json | JSONStream 'store.book[2]'

{ "store": {
"book": [
{ "category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95
},
{ "category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99
},
{ "category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
},
{ "category": "fiction",

],
"bicycle": {
