Detailed Description

A metaclass for `lsst.pex.config.Config`.

Notes
-----
``ConfigMeta`` adds a dictionary containing all `~lsst.pex.config.Field`
class attributes as a class attribute called ``_fields``, and adds
the name of each field as an instance variable of the field itself (so you
don't have to pass the name of the field to the field constructor).
