JSONLab now supports JSON Path syntax for slicing complex struct parsed from NeuroJSON.io data

[fangq]

We have refined the early implementation of JSON Path support, and now it can handle scan operator .. and one can perform flexible search of values inside a hierarchical struct/cell/containers.Map object (such as those parsed from NeuroJSON.io datasets).

For example, for a struct

{
    "book": [ 
      {
        "author": "Nigel Rees",
        "price": 8.95
      },
      {
        "author": "Evelyn Waugh",
        "price": 12.99
      }
    ],
    "bicycle": {
      "color": "red",
      "price": 19.95
    }
}

we can list all price subfield use jsonpath(data, '$..price'), list all book.author subfields as jsonpath(data, '$.book..author'); or the full information for the 1st book as jsonpath(data, '$.book[0]').

Because JSONLab is portable, this feature is supported in both MATLAB and Octave.
