• Datasets gained functions that simplify setting up access over various TDS services
• A catalog with a latest dataset now has a latest attribute that points directly to this dataset

Issues Closed

• Issue 136 - Simplify access to download services
• Issue 135 - Add datetime filtering of datasets
• Issue 134 - Improved dataset indexing
• Issue 102 - NCSS validate_query with no variables
