-- |  p.createInfobox()
-- ------------------------------------------------------------------
-- Build an infobox from the template arguments that called this module.
--
-- Parameters
-- ----------
-- * frame      – The current Frame object.
-- * cat        – Main category string to add before the page content.
-- * properties – A mapping of user‑argument names → SMW property keys
--                (optionally followed by a separator).  These are used
--                to set SMW properties via `mw.smw.set()`.
-- * order      – An ordered list that defines the order in which
--                sections appear inside the infobox.  Each entry must
--                match a key in `properties` or in the `infodata`
--                table below.
-- * subobjects - The table with names of templates responsible for subobjects creation
--                The module expects the the parent template parameter name **is equal** 
--                to the name of the template:
--                `...`
--                `|TemplateName={{TemplateName|...}}{{TemplateName|...}}`
-- Returns
-- -------
-- An `mw.html` object that contains:
--
--   * The main category (via `p.setCategory(cat)`),
--   * A fully populated infobox `<div>` with sections in the order
--     specified by **order** and styled according to **infodata**,
--
-- The returned HTML is rendered directly into the page where the module
-- was invoked.
