config object

When creating the store, you can specify an optional configuration object.

placeholders: number|Array<Object>

You can specify a number of placeholders or an array of placeholder objects that will populate the store until you add your first actual object or you call the #clearPlaceholders() method.

See the tests (tests/dataStore_test.js) to see how these methods are used.

Tests

We use mocha and chai. Run npm test to test the generators.
