Write report

Better document code

Merge receiveImage() and receiveGPSimage() functions into one

These two functions are almost identical and they could be merged into one with some extra checks. Do it for code readability.

Change echo packets' data into csv/xlsx file instead of txt

The echo packets' response times are saved in a txt file along with the packets' info, which isn't very easy to work with when making a graph. The response times must be saved in a spreadsheet, so that we can easily use them by scripts to make graphs.

Write .m script to make response times graph

Write a .m script in order to get echo packets' response times and make them into a graph. This will be done after issue #3 is done.

receiveGPSimage() doesn't show all the traces, but only one

StringIndexOutOfBoundsException in getGPSline() function.

Solved the infinite loop, but now there's a StringIndexOutOfBoundsException on line 315.

Make ARQMechanism() calculate the response time for each packet

Make ARQMechanism() write into csv file and make graphs. Check if it's correct.

java.io.FileNotFoundException error when writing into txt file

When receiveImage() tries to write into the txt files, this error occurs:

An error occurred.
java.io.FileNotFoundException: imageWithError.txt (Δεν ήταν δυνατή η προσπέλαση του αρχείου από τη διεργασία, επειδή χρησιμοποιείται ήδη από κάποια άλλη διεργασία)

However, the program continues execution and does create the txt files correctly. The jpeg files have no problem.
I can just comment out the txt files part since we no longer need it anyway, but it would be nice to know the reason behind this.
