Servicio para llamadas Ajax con jquery (soporte para callback)
TODO: Mejorar metodos 'get' y 'set' remover el uso del switch statement (sugerencia: utilizar object.hasOwnProperty)

//Ejemplo:
	//Variable para construccion
	var send = {
		url: "http://search.twitter.com/search.json?q=iscenigmax&count=10&callback=?",
		datatype: "jsonp"
	};

	//Declaracion del objeto y ejecucion
	var oAjax = new ServiceAjax(send);
	oAjax.execute(onSuccess,onError);

	//Lectura de datos
	function onSuccess(datos) {
		console.log(datos);
	}
    function onError() {
        console.log('Hubo un error');
    }
