V0.0.5b21 - 2020-02-24

Simplify, make better use of pillow (#193)

**Images**
- Use Pillow images throughout rather than our own `Image` abstraction (Closes #192 )
- The `encode` and `save` methods on our old `Image` class are now standalone methods
- There's no longer any need for a `arlunio._color` module, we can make use of Pillow's modes

**Other**
- Use the `appdirs` module to find the location we save the tutorial to, no longer any need for an `arlunuio._config` module
- Expose stdlib components at the `arlunio.lib` level

Merge pull request #189 from swyddfa/develop

V0.0.4b18 - 2020-02-15

Merging Shapes and Parameters, everything is now a Definition (#188)

- The `shape` and `parameter` decorators are no more, both are now share a common codebase in the `definition` system
- This does mean a small regression where drawing shapes no longer results in an image, but a mask. Although it feels like a step backward I hope this will lead to greater flexibility in the "second half" of the process of drawing an image 
- There is now an `arlunio.fill` function that can be used to recover the old behavior e.g.
  ```python
  import arlunio as ar
  from arlunio.lib.basic import Circle

  circle = Circle()
  image = ar.fill(circle(1920, 1080), color="ff0000")
  ```
- Parameter and Shape based entry points are no more, import what you need from `arlunio.lib.*` like a sane person
- Renamed the `autoshape` directive to `autodefn` and realigned it to the definition system. 
- Updated the reference section of the docs to expose everything in the standard library 

**VSCode**
- Collapsed all the tox related tasks into one that now allows you to choose the env from a dropdown list

V0.0.4b17 - 2020-01-26

The beginnings of the parameter system! (#185)

- Add a formal parameter system to `arlunio`
- Parameters are inputs to shapes that are dependent on the dimensions of the image being drawn. The typical use case for parameters so far has been to map a cartesian/polar coordinate system onto the pixels of an image in order for shapes to be defined w.r.t those coordinates.
- The new system adds an `@ar.parameter` decorator that will automatically define parameters based on the decorated function. See `arlunio/lib/parameters.py` for examples. 
- Highlights of the new system
  + Like shapes, parameters can take attributes as keyword only arguments
  + Support for derived parameters - i.e. instead of `width` and `height` as the input we could take other parameters that have already been defined. Any attributes in base parameters are automatically exposed on the generated class for the new parameter

**Future Work**
- So far the new system has not been integrated with the shapes system

**Other Changes**
- Add a dedicated `.gitignore`d folder for scratch, experimental notebooks
- Add VSCode task to launch notebook server in the scratch folder
- Add VSCode launch config to debug the current test file
- Tweak to some python specific VSCode settings

V0.0.4b16 - 2020-01-15

Import tweaks (#181)

- Changing import style for shapes from
  ```python
  import arlunio as ar
  ar.S.Circle()
  ``` 
  to 
  ```python
  from arlunio import Shapes as S

  S.Circle()
  ```
  Other functions like `arlunio.all()` should still be used with the `import arlunio as ar` style
- Also ensured all the "core" modules follow a consistent naming convention

- Added some tests around importing notebooks
