Fix - Removed the line break (\n) character at the end of the pillar data that was inserted by the python open() function; Added a booleen variable called raw_data, which if True will return to the old behavior and add a line break at the end of the pillar data
Adjusted the documentation for file tree following the addition of the line break fix
