* Circularly shifts the elements of an input ndarray by a specified number of positions along one or more ndarray dimensions.

* @param {ndarray} k - ndarray containing the number of positions to shift
* @param {Options} [options] - function options
* @param {IntegerArray} [options.dims] - list of dimensions over which to perform operation
* @throws {TypeError} first argument must be an ndarray-like object
* @throws {TypeError} second argument must be an ndarray-like object
* @throws {TypeError} options argument must be an object
* @throws {RangeError} dimension indices must not exceed input ndarray bounds
