/************************************************************ Mike Zhong CS575 Program 1 To compile, just use the Makefile provided by typing 'make', followed by './main' in the terminal. Or you can type 'g++ -o main CS575_myz540_p1.cc' and execute using './main' I did not have time to implement all the features and would not consider this my best work. I could not figure out how to implement pipelining but the input and output redirection works as long as there are spaces before and after the '<' or '>'. The '&' allows programs to run in the background but must be appended directly to the program name, like 'emacs&'. ************************************************************/
