Static-frame

Corrected issue in ``Quilt`` creation when given a ``Bus`` with ``Frame`` with ``datetime64`` indices.

Extended ``IndexAutoConstructorFactory`` to evaluate dtype from arbitrary iterables, not just arrays.

Improvements to consistency and performance of ``loc_to_iloc``.

Implemented ``max`` and ``min`` methods on ``IndexHierarchy``; related statistical methods now raise.

Enhanced support for ``fill_value`` as a ``FillValueAuto``, a mapping, or a sequence of fill values (per column) where appropriate.

Added ``Index.dropna()``, ``Index.dropfalsy()``, ``IndexHierarchy.dropna()``, ``IndexHierarchy.dropfalsy().

Added ``Index.fillfalsy()``, ``IndexHierarchy.fillfalsy()``.

Performance improvements for ``Frame.iter_group_labels()``, ``Frame.iter_group_labels_items()``, ``Frame.iter_group_labels_array()``, ``Frame.iter_group_labels_array_items()``.

Fixed usage of ``dtypes`` argument when encountering zero-sized data in ``Frame.from_records()`` and ``Frame.from_pandas()``.

Improved ``Frame.iter_tuple`` to not coerce types through arrays.

Added ``Frame.set_columns()``, ``Frame.set_columns_hierarchy()``, and ``Frame.unset_columns()``.

Added ``apply_element()`` and ``apply_element_items()`` methods to ``FrameAssign`` and ``SeriesAssign`` interfaces.

Added implementation of ``__array__()`` and ``__array_ufunc__()`` to all containers for better support with NumPy objects and binary operators.

Added ``Series.iter_group_array()``, ``Series.iter_group_array_items()``, ``Series.iter_group_labels_array()``, ``Series.iter_group_labels_array_items()``

Added ``Frame.iter_group_array()``, ``Frame.iter_group_array_items()``, ``Frame.iter_group_labels_array()``, ``Frame.iter_group_labels_array_items()``

Corrected issue when using binary operators with a `FrameGO` and a `Series`.

Corrected issue and performance of ``name`` assignment when extracting ``Series`` from ``Frame`` with an ``IndexHierarchy``.

Corrected more issues when calling ``IndexHierarchy.loc[]`` with another ``IndexHierarchy``, or when calling ``Frame.assign.apply`` when that frame has ``IndexHierarchy`` columns.

Corrected undesirable type coercion from happening in single-row selections from ``IndexHierarchy``.

Corrected issue when calling `IndexDatetime.loc[]` with an empty list.

Corrected issue when calling `IndexHierarchy.loc[]` with another `IndexHierarchy`
