}
### .getPathValue(object, path)

This allows the retrieval of values in an
object given a string path.

    var obj = {
        prop1: {
            arr: ['a', 'b', 'c']
          , str: 'Hello'
        }
      , prop2: {
            arr: [ { nested: 'Universe' } ]
          , str: 'Hello again!'
        }
    }

The following would be the results.

    getPathValue(obj, 'prop1.str'); // Hello
    getPathValue(obj, 'prop1.att[2]'); // b
    getPathValue(obj, 'prop2.arr[0].nested'); // Universe

@param {Object} object
@param {String} path
@returns {Object} value or `undefined`
