--[[
This module provides support to the automated taxobox system – the templates
Automatic taxobox, Speciesbox, Subspeciesbox, Infraspeciesbox, etc.
In particular it provides a way of traversing the taxonomic hierarchy encoded
in taxonomy templates (templates with names of the form
"Template:Taxonomy/TAXON_NAME") without causing template expansion depth errors.
]]

--[[=========================================================================
Limit the maximum depth of a taxonomic hierarchy that can be traversed;
avoids excessive processing time and protects against incorrectly set up
hierarchies, e.g. loops.

--[[========================== taxoboxColour ================================
Determines the correct colour for a taxobox, by searching up the taxonomic
hierarchy from the supplied taxon for the first taxon (other than
'incertae sedis') that sets a taxobox colour. It is assumed that a valid
taxobox colour is defined using CSS rgb() syntax.
If no taxon that sets a taxobox colour is found, then 'transparent' is
returned unless the taxonomic hierarchy is too deep, when the error colour is
returned.
Usage: {{#invoke:Autotaxobox|taxoboxColour|TAXON}}
