Script for installation and distribution.
You can use environment variable `SPTAG_RELEASE` to set release version.
If release version is not set, default to a development build whose version string will be `0.0.0.dev`.
## Prepare Environment ##
Install dependencies:
  $ pip install -U -r setup.txt
## Development ##
Build and install for development:
  $ python setup.py develop
Uninstall:
  $ pip uninstall sptag
Remove generated files: (use "--all" to remove toolchain and built wheel)
  $ python setup.py clean [--all]
## Release ##
Build wheel package:
  $ SPTAG_RELEASE=1.0 python setup.py bdist_wheel -p win_amd64
Where "1.0" is version string and "win_amd64" is platform.
The platform may also be "manylinux1_x86_64".
