Shell made by TheCharmingSociopath

File structure:

headers.h contains the declarations, libraries and constants
main.c contains the main function, and the main loop
core_functions.c contains the functions required for the working of the main file, like readline, execute, wait handler for background processes, etc.
rest .c files contain one command each, which is the file name, and contain all the remaining functions related to that file.
