We've changed the way plugins are activated, and removed the notion of
deactivated plugins.
Now plugins activate asynchronously.
When calling a plugin, it will be activated if it wasn't, and the call will wait
for the plugin to be fully activated.
* Improved debugging (back to using Flask's built-in mechanisms)
* Recursive model loading from json
* Added DEVPORT to Makefile
* Accept json-ld input. Closes#16
* Improved Exception handling in client
* Modified default plugin selection to only include analysis plugins
* More tests
* Added interactive debugging
* Better exception logging
* More tests for errors
* Added ONBUILD to dockerfile
Now creating new images based on senpy's is as easy as:
```from senpy:<version>```. This will automatically mount the code to
/senpy-plugins and install all dependencies
* Added /data as a VOLUME
* Added `--use-wheel` to pip install both on the image and in the
auto-install function.
* Closes#9
Break compatibilitity:
* Removed ability to (de)activate plugins through the web
