Memory leak report by Valgrind

[araujo88]

Here is the Valgrind report after running the application locally with the following command:
valgrind --leak-check=full --show-leak-kinds=all --track-origins=yes --verbose --log-file=valgrind-out.txt ./server

For testing the functions, the test file test1.py was utilized. Below is the report.
