Updated pTest.c to make it more C99 compliant.  Also, added proof-of-concept code for IO Redirection to child process.
ioRedir_Example.c uses example.txt as it's expected input file.  Hard coded into ioRedir_Example.c.
Merge branch 'master' of https://github.com/sethicis/cs485shell

Conflicts:
	pTest.c
	Silly comment conflict resolved.
