// The sendsms class can be used to send an SMS message via NowSMS.
//
// For additional information, please see http://blog.nowsms.com/2009/02/nowsms-java-example-send-sms-message.html
// 
// This class supports most of the URL parameters that are defined for NowSMS at the following link
// (plus additional parameters that have been added since that in newer releases of NowSMS):
//
// http://www.nowsms.com/documentation/ProductDocumentation/sending_messages/url_parameters_for_sending_messages.htm
//
// URL parameters are supported as methods for the sendsms class, with method names in all lower case.
//
// The init method initialises the SMS message object.
//
// The server method sets the URL address for the NowSMS server.
//
// The user and pass methods set the name of the user account ("SMS Users") on the NowSMS server.
// 
// The phonenumber method sets the recipient phone number (can be a comma delimited list or distribution list name).
//
// The text method sets the text of the SMS message.
//
// The send method submits the SMS message to NowSMS.
//
// The send method returns a list of message ids assigned for the submitted messages, with one message per line, in the following format:
//
//    MessageID=xxxxxxxxxxxxxx.req, Recipient=xxxxxxxxxxx
// 
//
// Example - Sending a simple text message:
//
//      sendsms.init();
//      sendsms.server = "http://127.0.0.1:8800/";
//      sendsms.user = "test";
//      sendsms.password = "test";
//      sendsms.phonenumber = "+9999999999";
//      sendsms.text = "This is a test message";
//      sendsms.send();
//
// Example - Sending a text message to a specific application port for a Java applet running on the phone:
//
//      sendsms.init();
//      sendsms.server = "http://127.0.0.1:8800/";
//      sendsms.user = "test";
//      sendsms.password = "test";
//      sendsms.phonenumber = "+9999999999";
//      sendsms.text = "This is a test message";
//      sendsms.destport = "9999";
//      sendsms.send();
//
// Example - Sending a WAP Push Message:
// 
//      sendsms.init();
//      sendsms.server = "http://127.0.0.1:8800/";
//      sendsms.user = "test";
//      sendsms.password = "test";
//      sendsms.phonenumber = "+9999999999";
//      sendsms.text = "This is a test message";
//      sendsms.wapurl = "http://www.nowsms.com/";
//      sendsms.send();
