0.2.5

Added:

• Added a "swapping" unary rule box to handle unary rules that change the direction of composition, improving the coverage of the BobcatParser.
• Added a --version flag to the CLI.
• Added a make_checkpoint method to all training models.

Changed:

• Changed the WebParser so that the online service to use is specified by name rather than by URL.
• Changed the BobcatParser to only allow one tree per category in a cell, doubling parsing speed without affecting the structure of the parse trees (in most cases).
• Made the linting of the codebase stricter, enforced by the GitHub action. The flake8 configuration can be viewed in the setup.cfg file.

Fixed:

• Fixed the parameter names in CCGRule, where dom and cod had inadvertently been swapped.
