…weepLib.py string.join() was removed in Python 3. Replace with the equivalent ''.join() syntax. Also removes the now-unused 'import string' statement. Fixes AttributeError: module 'string' has no attribute 'join' when running polar sweep analysis on Python 3.

Proposed Changes
string.join()was removed in Python 3, causing an immediateAttributeError: module 'string' has no attribute 'join'when running polar sweep analysis on any modern Python installation. Replacesstring.join(x.split(), "")with"".join(x.split())— identical behavior, Python 3 compatible. Also removes the now-unusedimport stringstatement.Related Work
