//Generic AJAX object for all types of HTTP get/post work			//
//Author: Debabrata Kar (dk.webtenet@gmail.com)						//
//Usage:															//
//	var ajax = new AJAX();											//
//	var arrParam = new Array();										//
//	arrParam['name1'] = 'value1';									//
//	arrParam['name2'] = 'value2';									//
//	arrParam['name3'] = 'value3';									//
//	ajax.getRequest(url, arrParam, responseHandler);				//
//	OR																//
//	ajax.postRequest(url, arrParam, responseHandler);				//
//																	//
//	NOTE: You do not need to escape() or encodeURIComponent() the	//
//	parameter names or values. AJAX will do it on its own.			//
//	You need to define responseHandler() function that will handle	//
//	response back from the server, be it XML or anything else		//
