GitLab

* Add Topic model
* Add PDB post-mortem debugging
* Add logger to plugins (`self.log`)
* Add NLTK resource auto-download
* Force installation of requirements even if adding doesn't work
* Add a method to find files in several possible locations. Now the plugin.open
method will try these locations IF the file is to be opened in read mode.
Otherwise only the SENPY_DATA folder will be used (to avoid writing to the
package folder).

* Merge branch '44-add-basic-evaluation-with-gsitk'
* Refactor requirements (add extra-requirements)
* Skip evaluation tests in Py2
* Fix installation with PIP
* Implement the evaluation service inside the Senpy API
* Connect Plugins to GSITK's evaluation module
* Add an evaluation method inside the Senpy Context
* Add the evaluation models and schemas
* Add Evaluation to the Playground, with a table view
* Add evaluation tests

GSITK doesn't support python2

* Remove '--use-wheel' flag
* Remove pip dependency
* Make GSITK an optional dependency

Remove standard aliases in __init__.py

In my machine this produces images that are ~300MB smaller.

Use the current build version in tests.
Tests will be slower (they require a build), but they will always contain the
latest dockerfile changes.

* Add sklearn example
* Fix test_case
* Add SenpyClientUse docs

a.k.a. The wise men edition

* Add Box plugin (i.e. black box)
* Add SentimentBox, EmotionBox and MappingMixin
* Refactored CustomDict

* Fixed Options for extra_params in UI
* Enhanced meta-programming for models
* Plugins can be imported from a python file if they're named
`senpy_<whatever>.py>` (no need for `.senpy` anymore!)
* Add docstings and tests to most plugins
* Read plugin description from the docstring
* Refactor code to get rid of unnecessary `.senpy`s
* Load models, plugins and utils into the main namespace (see __init__.py)
* Enhanced plugin development/experience with utils (easy_test, easy_serve)
* Fix bug in check_template that wouldn't check objects
* Make model defaults a private variable
* Add option to list loaded plugins in CLI
* Update docs

* Change names of plugins to avoid repetitions (we may have to revert this)
* Make subprocess log private

* Refactored BaseModel for efficiency
* Added plugin metaclass to keep track of plugin types
* Moved plugins to examples dir (in a previous commit)
* Simplified validation in parse_params
* Added convenience methods to mock requests in tests
* Changed help schema to use `.valid_parameters` instead of `.parameters`,
which was used in results to show parameters provided by the user.
* Improved UI
    * Added basic parameters
    * Fixed bugs in parameter handling
    * Refactored and cleaned code

Extra parameters of the plugins didn't get a box all the time.
