--[[*************************************************************************
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.

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.

Function to determine whether the taxon name derived from the name of the

(passed in the parameter linkText).
The taxon name may have any of the formats:
* baseTaxon/qualifier
* baseTaxon (disambig)
* baseTaxon (Subgenus) [distinguished by the capital letter]
* a qualifier may be present after the previous two formats.
Examples of matches (baseTaxon ~ linkText):
* Pinus ~ Pinus
* Pinus sect. Trifoliae ~ Pinus sect. Trifoliae
* Pinus sect. Trifoliae ~ ''Pinus'' sect. ''Trifoliae'' [italic markers ignored]
* Pinus sect. Trifoliae ~ P. sect. Trifoliae [abbreviated genus name matches]
* Bombus (Pyrobombus) ~ Bombus (Pyrobombus)
* Bombus (Pyrobombus) ~ B. (Pyrobombus)
* Bombus (Pyrobombus) ~ Pyrobombus [link text may just be the subgenus]
* Heteractinida ~ "Heteractinida" [double-quotes are ignored in link text]
* "Heteractinida" ~ Heteractinida [double-quotes are ignored in base taxon name]
* Incertae sedis ~ anything [link text is ignored for matching in this case]
* Cetotheriidae with qualifier=? ~ Cetotheriidae (?)
