Christian Klotz 748ae8f06a Add Spanner driver
Support for Google Cloud Spanner, closes #172. Includes example migrations ported over from the PostgreSQL driver.

In all examples provided by Google I’ve come across, camel-case is used for table names, columns, etc. Hence the examples use this naming convention.
