- Initial version after excising from hvc
(https://github.com/NickleDave/hybrid-vocal-classifier/commits/0c50144d75e3a3205db82add8b48302edbbed511/hvc/koumura.py)

changed
- The library now limits itself to returning annotation in a data structure
similar to what's used in the BirdsongRecognition code.
+ e.g. `parse_xml` no longer returns an "annotation dictionary"
+ instead, the [conbirt package](https://github.com/NickleDave/conbirt)
handles translating the data structures to the "annotation dictionary"
structure that it uses internally
- Convert tests to Python unittest format (instead of using PyTest library)

added
+ Write README.md with usage
+ to help work with `conbirt` package, the `parse_xml` function
now has parameters to allow returning the paths to the .wav files as
absolute paths, but by default it returns just the file names, as
specified in the `Annotation.xml` files.
