* This is a single php page and set of functions that, when given the right
* data will return a set of formatted MSN search results. Requires NuSOAP,
* located at http://sourceforge.net/projects/nusoap/.
* Stick this file into a folder in your server along with NuSOAP
* library and point your browser there for action. Don't forget to get
* an MSN Application ID (see http://search.msn.com/developer)
