 * Retrieve the value at a given path.

 * Paths can be defined by a string an array. The path parameter also accepts a function that will be used as a selector against the data.

 * @function
 * @since v0.0.3
 * @category data
 * @param {Array|string|number|Function} path The path to use.
 * @param {Object} value The value to retrieve the nested property from.
 * @returns {*} The data at `path`.
 * @example
 *
 * get(['a', 'b'], {a: {b: 2}})
 * //=> 2
 *
 * get(['a', 'b'], {c: {b: 2}})
 * //=> undefined
 *
 * get('a', {a: {b: 2}})

 * get('a.b', {a: {b: 2}})

 * get('[0]', [ 1, 2 ])
