GABBs 2.0 Release

Version 1.0 of the Workflow Engine is now deployed and available for use on MyGeoHub. The workflow engine is installed as a Python package and can be used from the Jupyter notebook tool.

The workflow engine takes a high-level workflow specified in YAML format and automatically executes the corresponding data wrangling processes on the Halstead cluster at Purdue. The YAML syntax and semantics of workflows and a description of the workflow engine can be found in the documentation.
