bitfieldpy 0.0.9

# bitfieldpy
Python3 porting of [bitfield](https://github.com/drom/bitfield) with all respect
to the original designer.

`python3 bitfield.py bitfield.json > bitfield.svg`

The library works exactly same as original program, except some of command line options.

- Added `-s/--svg` to output to a file in addition with redirecting(`>`)
- More strict to JSON format

# Install
The library requires svgwrite and attrdict libraries.

- `pip3 install bitfieldpy`(install archive from pypi)
- `pip3 install git+https://github.com/K4zuki/bitfieldpy.git`(edge/developing version)
