* Merge recent changes from upstream. (#1)

* Added Finances API Feature

* Don't do automated deployments via Travis (for the moment)

* Update README.md badges

* InboundShipments, next_token_action decorator, and some style cleanups. (#33)

* Testing out git commits from VS Code

* Reverting the test commit

* Adding VS Code settings to gitignore.

* Style fixes

* MWS.enumerate_param deprecated: now using utils.enumerate_param and utils.enumerate_params

* InboundShipments fleshed out; added `utils.next_token_action` decorator; deprecated separate methods for `...by_next_token()`

* Bugfix, rename `_enumerate_param` to `enumerate_param` (no need for private)

* Fix for next_token issues.

* TravisCI flake8 complaining, fixes.

* Minor flake8 complaint.

* Hack to get flake8 to stop complaining.

* Strip pylint disables to clear line length issue.

* Correction to keyed params, now tests every item in values sequence to ensure all are dicts.

* Add tests for param methods in utils.

* Add test for next token decorator.

* Adding 'InboundShipments' to `__all__`

* Assigning response a default in __init__ for DictWrapper and DataWrapper

* Unneeded line breaks removed + docstring formatting

* Comment corrected. They're tuples, not sets.

* Finances methods updated to use next_token_action decorator

* Ignore VS Code settings

* Remove unneeded spacing

* Add __iter__ method for ObjectDict to allow simpler iteration, without having a problem when the node is a single ObjectDict instead of a list.

* Update docstring for `fromstring`

* Variable name correction (linter complaint)

* Comment and docstring overhaul

* Remove get_timestamp, replace with more standard datetime.datetime.utcnow().isoformat()

* Add `assert_no_token` test for methods that use a next_token.

* Rename _parse_item_args to parse_item_args (no need for it to be "private")

* Re-write for calc_request_description to make some more sense.

* Set up testing flag for params to request method.

* Test name and comment cleanup

* Contents of __all__ sorted alphabetically (pet peeve)

* Include assert_no_token as part of decorator test

* Add initial modules for testing request methods

* rename test modules (linter complaint)

* Inventory tests added.

* Remove independent service status test (moving towards shared service status param test for each class)

* Move service status test to tests.utils.CommonTests, to be inherited by each request test case from here on.

* Set isoformat timespec to seconds (don't explicitly need milliseconds, and omitting them makes testing simpler)

* Refining common tests, using Inventory class to test the tests.

* Bug: should not change the test param to false.

* Bugfix: timespec is only available in 3.6+.  Replacing with microsecond=0 solution to produce desired result.

* Stubs for test suites for existing APIs

* Docstrings. Docstrings everywhere.

* Bugfix: incorrect super for 2.7

* Documentation updated with gettingStarted section
