EXECUTION NOTES:
Because of my parsing method I have one alteration to my input.
input and output redirection are always specified directly after the program name even while specifying multiple pipes, for example:
program1 ^ infile $ outfile
pargram1 ^ infile -> program2 -> program3 $ outfile

Job Control must always be executed with background ("!") on.
Only job groups from 0 to 9 are supported.
