/* Lossless_UDP testclient
* A program that connects and sends a file using our lossless UDP algorithm.
*
* Best used in combination with Lossless_UDP_testserver
*
* Compile with: gcc -O2 -Wall -o test ../core/network.c ../core/Lossless_UDP.c Lossless_UDP_testclient.c
*
* Command line arguments are the ip and port to cennect and send the file to.
* EX: ./test 127.0.0.1 33445 filename.txt
