Added functions to check input from the terminal. escape_to_terminal() breaks when presented with more than one argument.
Fixed issue 7. Found issue 9 which is not urgent. Pull request to master as this code is stable.
Merge pull request #10 from bensaward/testing

Added interpreting functions to the program which are stable, currently "quit" is the only recognized command.
