                   Ajax Utility JavaScript Library

  This library supports these functions: 

  getText(urlToCall, functionToCallBack) 
    Uses the GET method to get text from the server. 

  getXml(urlToCall, functionToCallBack) 
    Uses the GET method to get XML from the server. 

  postDataReturnText(urlToCall, dataToSend, functionToCallBack) 
    Uses the POST method to send dataToSend to server, gets text back. 
    Pass the data to send in parameter/value pairs like this: "value=100".

  postDataReturnXml(urlToCall, dataToSend, functionToCallBack) 
    Uses the POST method to send dataToSend to server, gets XML back. 
    Pass the data to send in parameter/value pairs like this: "value=100".
