All Aboard The Annotator Train

New features:
- Drop rows (locally) or columns (locally or remotely on Synapse) from a file view.
- Add to the scope of a Pipeline data view.
- Get default columns which are automatically created when creating a file view for a given scope.

New files:
- bin/create_empty_fileview.py
- bin/sync_manifest.py
- tests/sampleFile.csv
- tests/sampleMeta.csv
- tests/unit/conftest.py
- tests/unit/test_utils.py

Schema Integration

Changes in this release:

• Added some standard files (.gitignore, tests).
• Pipeline objects can now work with predefined schemas and warn users when publishing file views with malformed schema values.
• Scripts added for maintaining Synapse annotation standards.
• PEP 8 compliance (mostly).

Initial Release

Introduces the Pipeline object and utils module to help make adding and modifying annotations using file views simple. No tests yet, so use with care. Since changes are entirely local until pushed to Synapse there's not much risk in irreparably breaking anything.
