> In many environments, schema changes to Phoenix tables are applied in batches 
> associated with a version of an application. (For example, v1.0 of an app may 
> start with one set of CREATE statements, v1.1 then adds some ALTER 
> statements, etc.) 
> It can be useful to be able to look up the latest app version in which a 
> table or view was changed; this could potentially be added as a feature of 
> the Schema Tool. 
> This change would add an optional property to CREATE and ALTER statements, 
> SCHEMA_VERSION, which would take a user-supplied string. 
> This is also a pre-req for PHOENIX-6227, because we would want to pass the 
> schema version string, if any, to an external schema repository in 
> environments where we're integrating with one.
