try switching to use eulxml mods class
bump the eulxml requirements to 0.19.0
remove some code that we don't need in mods.py anymore
bump version to 0.4
IrMetadata can now have multiple collections (as it should)
add MODS_NAMESPACE to mods module
support multiple titleInfo elements, and the display label. Note: have to support these elements here until eulxml gets them added.
override origin_info so we can have dateOther fields
Added commonly used xpath 'Collection' do the base mods we get from eulxml
Forgot to run test.  Easy fix.  Always run tests.
override Subject and add hierarchicalGeographic node
fix missing ROOT_NAME
support displayLabel attribute in mods:originInfo
Update requirements.txt & setup.py because we now depend on eulxml 0.20. Remove some code that's been added upstream. Add some test code.
Initial work on index_data() - so that we get a dict of solr fields & data to use for indexing.
Fix a couple errors & add a couple tests.
change a test to make it compatible with python 2.6
Solrize specific note fields based on type & displayLabel.
Add displayLabel note field & change slugify a bit.
Update displayLabel handling & change slugify a bit.
