New on this release:

API Changes:

Bug Fixes:

- Fixed documentation malfunctions

Others:

- general style/flake8 pass;
- new tests for the new functions.

New on this release:

**API Changes:**
* Removed `across_groups` parameter from `get_user_id` because it was irrelevant

**Bug Fixes:**
* Fixed behavior where `across_groups` parameter was always set to `True`

New on this release:

**API changes**

- added `ezomero.ezconnect()`, a function to make generating `BlitzGateway` objects easier
- Many functions now have a `across_groups` parameter (defaulting as `True`) that allows them to work transparently across groups. For example, `get_image()` receiving an image ID outside the current connection group will still work seamlessly as long as the connected user has permissions to read that image.
- `post_map_annotation()` has been changed to only accept a single ID, for consistency with the other `post` functions.

**Non-API changes**

- Testing is now done automatically for new pushes and pull requests (with a badge on readme!) via Github action
- Group/project/dataset structure for testing has been overhauled
- Docs are now being auto-generated by Sphinx

This is the first release in which the tests are working (pytest).
