Static-frame

Fixed issue in ``Series.drop`` when the ``Series`` has an ``IndexHierarchy``.

Calling ``Frame.from_series`` with something other than a ``Series`` will now raise.

Calling ``Index.from_pandas``, ``Series.from_pandas``, and ``Frame.from_pandas`` now raise when given a non-Pandas object.

``StoreConfig`` given to ``Bus.to_xlsx``, ``Bus.to_sqlite``, and ``Bus.to_hdf5`` are now properly used.

Introduced the ``Batch``, a lazy, parallel processor of groups of ``Frame``.

``Index`` and ``IndexHierarchy`` ``intersection()`` and ``union()`` now accept ``*args``, performing the set operation iteratively on all arguments.

Revised default aggregation function to ``Frame.pivot``.

Fixed issue in writing SQLite stores from ``Frame`` labelled with strings containing hyphens.

Added `include_index_name`, `include_columns_name` to ``Frame.to_delimited``.

Added `include_index_name`, `include_columns_name` to ``StoreConfig`` and ``Frame.to_xlsx`` interfaces.

Added `index_name_depth_level` and `columns_name_depth_level` to `Frame.from_delimited` and related methods.

Added `index_name_depth_level`, `columns_name_depth_level` to ``StoreConfig`` and ``Frame.from_xlsx`` interfaces.

Improved implementation of ``Frame.pivot``.

Removed class-level documentation injection, permitting better static analysis.

Corrected issue in appending tuples to an empty ``IndexGO``.

Added ``Frame.from_clipboard()`` and ``Frame.to_clipboard()``.

Added ``Frame.pivot_stack()`` and ``Frame.pivot_unstack()``.

Fixed flaw in difference operations on ``IndexDatetime`` subclasses of equivalent indices.
