"""
Get a child group or child dataset, a selection of child groups, or load and
return the current group.

Three cases are supported:

- String name: The child group or child dataset of that name is returned.
- Class such as ``NXdata`` or ``NXlog``: A dict containing all direct children
with a matching ``NX_class`` attribute are returned. Also accepts a tuple of
classes. ``Field`` selects all child fields, i.e., all datasets but not
groups.
- Scipp-style index: Load the specified slice of the current group, returning
a :class:`scipp.DataArray` or :class:`scipp.DataGroup`.

Parameters
----------
sel:
Child name, class, or index.

Returns
-------
:
Field, group, dict of fields, or loaded data.
