1.6  2016-01-05
* We now implement FoLiA spec 1.4
* ABI breakage. .so name bumped to 6.0.0
  reason:
  - new properties added
  - implementation of generateId() is chaneged
* enhancements to folialint. Saving a document with --strip also
  implies canonical output
* some bug fixes

  - check empty attributes in Feature() construction

1.4  2016-10-18
[Ko van der Sloot]
* Now fully implements Folia spec 1.3.2
   - multiple ForeignData nodes
   - added more Feature nodes, like Polarity, Strenght
   - Source, Target, Relation, Predicate, Sentiment Statement,
     Observation Annotations and Layers.
   - Comment node
   - better version checking.(and a bit relaxed too)
* some bug fixes and code improvement.
  - str() works more as expected
  - fixup ref 'id' vs. 'xml:id'

     - small bug fixes

1.0  2016-03-09
[Ko van der Sloot]

  * a lot of small code updates and refactorings
