//88 How it works:                                               88//
//88 Finds all the tables in a document                          88//
//88 Loops through every table                                   88//
//88 Finds all the rows in the current table (<tr>)              88//
//88 Loops through every second row                              88//
//88 Checks for the presence of the class attribute              88//
//88 If there is one give it a space seperated class of "even"   88//
//88 If there isn't one it just gives it a class of "even" with- 88//
//88 out the space separation.                                   88//
