- CI support with Travis and Appveyor have been set up.
- The packages `__init__` file checks if the users Python version is supported by this release and prints a warning otherwise.
Import datacite script
- the odmltools.importers package contains a conversion tool from a DataCite XML file (kernel version 4) to odML.
- this importer handles the latest datacite namespace (http://datacite.org/schema/kernel-4) by default. Further namespaces can be added via the command line to also ensure conversion of previous DataCite version files.
- on install a command line convenience script `odmlimportdatacite` is set up for this conversion.
