History:
- Derived from package org.pentaho.di.trans.steps.terafast
- Modified for TPT by Kevin Hanrahan (cfikevin/pentaho-kettle forked
from pentaho/pentaho-kettle)
- Moved the core pentaho-kettle classes into a plugin project
pdi-teradata-tpt-plugin (using mattyb149/pentaho-plugin-skeletons)
- Using annotations instead of plugin.xml
- Renamed the step to 'Teradata TPT Insert Upsert Bulk Loader', minor
label changes

Notes:
- To create a Marketplace zip, build with target 'package' to create
dist/TeraDataBulkLoader.zip (includes package-res/version.xml)

TODO (see also http://jira.pentaho.com/browse/PDI-10216): 
- Code review: remove system.out, print stacktraces etc.
- Build: Review the usage of pentaho-plugin-skeletons (icon in
package-res), mattyb149 updated pentaho-plugin-skeletons since it was
used
- UX: needs changes (tabs look different, some buttons/labels are too
narrow) and review  
- QA: check if variables are resolved correctly, test save to/from
repository etc.
- Doc: Finalize documentation:
http://wiki.pentaho.com/display/EAI/Teradata+TPT+Insert+Upsert+Bulk+Loader
- Check maturity level, upload to marketplace
