added testing.py
Added heel sequence parameters and updated CSV/print outputs to display heel sequences if given.
Deleted empty testing.py file.
edited position of heel sequence output from end of sequence string to beginning.
Removed case-sensitivity for heel sequences in Primer_design.py, added runner.py

Heel sequences now case insensitive at input; will output whatever case
was input.

Runner.py will run Primer_design.py with preset args for params (used
for my own personal ease-of-use).
Removed erroneously included debug code
Ran autopep8 over Primer_design.py

Command: autopep8 Primer_design.py --in-place

Generated pre and post log using: pep8 --quiet --statistics
