JSON-file-pointer

Simply returns line/column location in a js-file with JSON from path:

``js
const jsonPointer = require('json-file-pointer');

const jsonExample = require('fs').readFileSync('simple.deps.js');

/**
* ({
* shouldDeps: [
* { block: 'js' },
* { block: 'page', elem: ['header', 'body'] }
* ]
* });
*/

console.log(
jsonPointer.getLocationOf(jsonExample, ['shouldDeps', 1, 'elem', 0])
// or: getLocationOf(jsonExample, 'shouldDeps[1].elem[0]')
);

// { line: 4, column: 33 }
`

Also works with module.exports and exports` form.
