1. better bin/mongodb-datasets.js: now can do cat schema.json | mongodb-datasets.js --size 10 > out to write the result to file. All supported commands are:

• --size=<number> - the size of generated docs
• --populate [--uri <db uri> --collection <name>] - whether to populate the result to mongodb, default is false
• --raw=true/false whether to format the json docs, default is true
• made Populator also a Transform stream to support chaining more pipes after it
• enhanced the scoping feature to support access to parent-level variables by this._$parent.<var>

[TZ2016]

Updated all the tests to use the new createGeneratorStream API call.
