Hello Bash Testing

Testing: Hello, Bash!

# FUNCTION: testBashVer = Test for min required bash version.
# FUNCTION: testBashHello = Test for expected bash output.
# FUNCTION: bashHello = Print the following to the terminal ["Hello, Bash!" ]
# FUNCTION: printManPage = Print out a linux man page for offline reference.
