* Remove six for PY2 compatability since our dependencies are not, PY2 is legacy. * Removed usages of utils from future/past libraries since they are deprecated. This includes 'from __future__ ...' and 'from past...' statements. * Removed compatibility imports for PY2, switched from six imports to standard library imports. * Removed utils code blocks that handle operations depending on PY2/3 versions. * Removed 'from __future__ ...' lines from templates/code generators * Used PY3 syntaxes in place of PY2 compatible blocks. eg: metaclass
