Nothing Changed, Still learning git
Merge https://github.com/carlsoncs/CS-2240

Conflicts:
	Homework/3. Shell/Working/shell.c
Worked in Shell on the structure for dealing with multiple pipes, and commented out some debuggingprint statements etc.
nothing much
Updated shell function to deal with backgrounding, updated exec and execMore to actually execute the commands passed to them.  Nearly working shell, bugs still causing problems though, and redirection isn't working right.
forgot to save before last commit.
After debugging I made a number of minor changes to the code.  It may be worth looking at the diff of this and the previous commit to see what I changed.
