What works and doesn't

Successfully tested: As long as the command works alone in Pish, .pishrc is fully functional Single commands such as "echo hello world" run fine Pipes split commands into parts Signals are ignored Built in commands such as cd and exit work Commands are forked and then exec'd after being split by pipes if any Pish prompt works and parses properly

Unsuccessfully tested: Redirection operators are found, but not acted upon Pipes don't redirect i/o into other commands (i.e. ps aux | grep 'Z') Environmental variables being handled by Pish
