DataPrep.sh

1. I made the overall big changes to code structure
2. I got rid of a lot of the dicom processing steps, (but left it open for addition in the future)
3. Not commented all the way through.

Here is some reading based on what I think would be confusing about my coding habits:

ex. { command || command2 ;} https://www.gnu.org/software/bash/manual/html_node/Command-Grouping.html

ex. command1 && command2 http://landoflinux.com/linux_bash_scripting_boolean_operators.html

ex. var=$(command1 arg1) http://unix.stackexchange.com/questions/48392/understanding-backtick

ex. printf "%s\n" "word1" "word2" http://wiki.bash-hackers.org/commands/builtin/printf
