Restructure datapackage as below:

| - data/
|
| - bindfit/
|   algorithm.json
|   algorithm.py
|   - containers/
|   - formats/
|   - interfaces/
|   - views/
|   - resources/ - DELETE THIS - can be bootstrapped from signature
|
| - bindfit.run - created on run???
|   configuration.json - bootstrapped from algorithm signature defaults
|   - resources/ - created on execution success?? output resources to here
|
| datapackage.json

Example workflow:

• ods init - creates (default) run directory, bootstraps default configuration and resources, adds configuration to datapackage.json:configurations array
• ods load data - loads data into resource
• ods run
