v0.2.0

Features

• target-finder-cli targets <file...> subcommand has been added.
• Added support for specifying the maximum blob width in the blobs
  subcommand.
• CLI can have arguments added directly in target_finder.cli.run(...) that
  override sys.argv.

Breaking Changes

• The target-finder-model
  module must be installed separately, since the model is now treated as an
  external dependency that is not listed in setup.py.
• Renamed the max_length keyword argument in target_finder.find_blobs(...)
  to max_width to match the existing min_width argument.

Fixes

• Fixed the default padding setting on the blobs subcommand to match the
  default value for target_finder.find_blobs(...).
• Confidence numbers for targets are now correctly returned as standard floats
  instead of numpy floats in target_finder.find_targets(...).

Chores

• Added tox for unit testing.
• Enabled code coverage on tests.
• Dependencies are listed inside of setup.py instead of in their own file.
• Uploading releases is now done by Travis CI.
