Dr. Blythe:
I have a feeling my program could be written in a fraction of lines of code, but to do so
I think I need to figure out how to use signal better. While my code is messy, it 98% works
with that said here are the bugs..

    * Pipe can run but it gets stuck and user will have to ctrl + C to exit program
    * the second half of pipe can only read a 1 work command
    



Steps processed:
1. Made if else structure
2. started cd implementation
    * Need to find command to return file name, after that can complete this task
    * Answer was... I needed to type cast the function (_argArray = (string*) com.args();)
3. Researched and worked out execp, it works with single word commands.
    * Need to test and fix to work with multi word commands
    * created a for loop to fix the multi argument read in. didnt work, currently commented out
4. The backgrounded function was completed by rearanging the position of things, it is tested and functional
    * If I fix 3 to be bugless this will need to be revisited **
5. After the big repostioning of this file there was a lot of bug fixing and adapting,
execvp stoped working for a bit but after a night of fixing everying except backgrounding and pipe works.
    (Personal thought, where it is at looks messy right now, but I have just over 24 hours to
    complete so if I finish early I will go back and try to clean up the code so there is not so much repetition)
6. Pipe is mostly working, unsure if its a requirement but it can only take in one word commands after the pipe
    Also if the pipe is ran you cannot exit the terminal
7. I am going to try to make is backgrounded work in a less brute force way.
