#759 Codeclimate config (#843)

* Initial stab at CodeClimate configuration file

* Enabling everything to analyze usefulness of output

* Disabling some useless metrics

* Ignore static directory

* Disable similar code metric

* Exclude identical code in test files

* glob

* Reduce max file lines to 750

* Fix exclude pattern

* Exclude t/

* Up max file length + remove t directory

* Ignore t/ directory only for identical code metrics

* Exlcude patterns to exclude paths

* testing

* more testing

* reindent

* Revert back to excluding t directory
