Standalone waterline unable to use getDatastore() and use SendNativeQuery()

Hi,

I am using Waterline Standalone, from the documentation it said I can use raw SQL by using `SendNativeQuery()`, but to do that I need to get datastore first, but every time I use
`collection.datastores` or 'collection.getDatastore('default')`, it said it is not a function.

Is there any required step to use SendNativeQuery without using Sails?

Review the standalone Waterline documentation and the references to `collection.datastores`, `collection.getDatastore('default')`, and `SendNativeQuery()`. Reproduce the reported calls outside Sails; done means either a documented setup enables the call or the standalone limitation is clarified.
