--[[=========================================================================
Italicize a taxon name appropriately by invoking italicizeTaxonName.
The algorithm used is:
* If the name has italic markup at the start or the end, do nothing.
* Else
  * Remove (internal) italic markup.
  * If the name is made up of four words and the third word is a
    botanical connecting term, de-italicize the connecting term and add italic
    markup to the outside of the name.
  * Else if the name is made up of three words and the second word is a
    botanical connecting term or a variant of "cf.", de-italicize the
    connecting term and add italic markup to the outside of the name. 
  * Else just add italic markup to the outside of the name.
