0.2.7

[ianyfan]

Added:

• Added support for Japanese to DepCCGParser. (credit: KentaroAOKI Add Japanese support to DepCCGParser #24)
• Overhauled the CircuitAnsatz interface, and added three new ansätze.
• Added helper methods to CCGTree to get the children of a tree.
  Added a new .tree2diagram method to TreeReader, extracted from TreeReader.sentence2diagram.
• Added a new TreeReaderMode named HEIGHT.
• Added new methods to Checkpoint for creating, saving and loading checkpoints for training.
• Documentation: added a section for how to select the right model and trainer for training.
• Documentation: added links to glossary terms throughout the documentation.
• Documentation: added UML class diagrams for the sub-packages in lambeq.

Changed:

• Dependencies: bumped the minimum versions of discopy and torch.
• IQPAnsatz now post-selects in the Hadamard basis.
• PytorchModel now initialises using xavier_uniform.
• CCGTree.to_json can now be applied to None, returning None.
• Several slow imports have been deferred, making lambeq much faster to import for the first time.
• In CCGRule.infer_rule, direction checks have been made explicit.
• UnarySwap is now specified to be a unaryBoxConstructor.
• BobcatParser has been refactored for easier use with external evaluation tools.
• Documentation: headings have been organised in the tutorials into subsections.

Fixed:

• Fixed how CCGRule.infer_rule assigns a punc + X instance: if the result is X\X the assigned rule is CONJUNCTION, otherwise the rule is REMOVE_PUNCTUATION_LEFT (similarly for punctuation on the right).

Removed:

• Removed unnecessary override of .from_diagrams in NumpyModel.
• Removed unnecessary kwargs parameters from several constructors.
• Removed unused special_cases parameter and _ob method from CircuitAnsatz.
