function [ status ] = sendUDP( data, IP, port )
%sendUDP Send an one dimensional array of type uint8 data over an UDP connection using a java DatagramSocket
%
%Inputs
%     Data: 1-D array of type uint8 data to be sent
%     IP Address (optional): IP Address of the machine that will receive the data as a character array. Default is '127.0.0.1' (local machine)
%     port (optional): Port on the receiving machine where the data will be sent. Default is 49009 (XPlaneConnect). In general use 49009 to send to the plugin
%
%Outputs
%	status: If there was an error. Status<0 means there was an error.
%
%Use
%	1. import XPlaneConnect.*;
%	2. data = uint8([1:20]);
%	3. #Send the data array to port 49005 on the computer at IP address 172.0.100.54.
%	4. status = sendUDP( data, '172.0.100.54', 49005 );
