Instructions To Run in project directory terminal:

1. $ make run
2. $ make valgrind
3. Or you can figure something else out...

Important Notes:

• I suggest collapsing all the code / comments if your editor supports that.

• I have modified his splt_cmd_line() function. I added comments to it that
  hightlight his use of strtok_r() and how I have modified it.

• I #defined a preprocessor directive, DEBUG, to sort of make use of the functionality behind the verbose flag from Project 1.

• main() will loop on user input, calling his splt_cmd_line() function repeatedly
  to split the line into commands, separated by pipes, |, and will then call my
  sgt_major_pipage() function which will loop through each command in commands,
  further delimiting each command into argv-like arrays, separated by whitespace,
  calling my handle_single_command() function to execute each command as if it
  were a stand-alone command.

• Most recent update: added logic for attempting arbitrary pipes... DOES NOT WORK :(. Currently commented out said logic so that it can can still be ran to test running stand alone commands found between pipes.

• I have often executed the following sequence of commands while testing / creating this logic:

1. $ make valgrind
2. $ echo hello | echo hi | ls
