Changes

Q3: Are we supposed to make two brand new files named consolelineedit.cpp and consoleplus.h and compile them with the original console.cpp and console.h or are we supposed to modify the original console.cpp and console.h files and name them consolelineedit.cpp and consoleplus.h?

*Answer: Keep console.h and consoleplus.h as separate files, same with console.cpp and consolelineedit.cpp.
