Detailed Description

Compute the level 20 HtmIndex for the catalog.

Notes
-----
This functor was implemented to satisfy requirements of old APDB interface
which required the ``pixelId`` column in DiaObject with HTM20 index.
The APDB interface had migrated to not need that information, but we keep
this class in case it may be useful for something else.
