Toucan-Tools 0.4

# 1-4 Performace Task
### Client 4: Developer

## Installation
To use, `$ pip install Toucan-Tools`. From there, all of the command-line tools will be available for use anywhere on your machine.

## Usage
A main script (run from terminal) processes an image with a library of image tools. To run: `$ toucan imagefile.jpg -t blur`. This will display a window showing the image with the applied tool.

### Tools to start out with
* Grayscale Coloring
* Circle/polygon Packing
* Thermal Coloring
* Number Visualization (colored mosaic)

### Conventions
All transformation tools are located somewhere in the tools package, and can all be called on from the root of the package. To follow the zen of python package structure: the less dots the better.
