* "highlight" takes an array of search results and an array of search terms.
* For each search term, it strips the term to its stem and then it uses a regular expression to search
* for all matching similar words in each result and put them in a highlighted <span> element.
*
* An alternative way of doing this would be to take each word of the result and "stem" it, then compare it
* to each search term, but this was rejected because it is a) uglier than this (if that's even possible) and
* b) would take forever.
