-- This module renders the {{Species _link}} template.
--- @module SpeciesLink
-- https://hoodedhorse.com/wiki/Against_the_Storm/Template:Species_link
--
-- This template #invokes SpeciesLink.renderLink(frame), below.
--
-- The template requires an argument, the name of the Species to which to link.
-- Optionally, the template accepts a second argument to change the size of the
-- icon that accompanies the text hyperlink. The Species is passed to
-- Module:SpeciesData, which is used to identify the wiki page to link to. It
-- also handles some basic normalization to tolerate small mistakes in spelling,
-- spacing, or punctuation.
--
-- Using the data returned, this module creates an icon and the name of the
-- Species, and wraps both in a link to the Species's wiki page. If no icon
-- size is specified, the icon will default to a size appropriate for display
-- in-line with other text.
--
-- IF there is a known Species that does not have an icon (might be the case if
-- the data is being updated), then a question-mark icon will take the place of
-- the Species's icon. This is so that people using this template will not
-- mistake a missing icon for an issue with this template and can efficienty
-- troubleshoot.
--
-- The icons are sized consistently by using existing wiki templates, {{ImgS}},
-- {{ImgM}}, etc. The sizes of icons are not stored or known by this module.
