/* Added by Eli Ribble May 23, 2008. Originally I wanted to add this to the custom files for user 255, glocker.com, as per their request to add the school district search. Unfortunately, I couldn't figure out how to easily get a custom ne_functions.js file to be read from the directory structure, so I opted to put the function here, in the general file, because I didn't see any harm in having additional functions that are only used by a single user. Sure, it'd be way better to have it with the other custom files, but I'm uncertain if the system can intelligently use it, so I'm leaving it here for now. Also, I've modified the other init functions to properly hide the school district search tab, even though it won't be present in any other site. */
