Check for supports_execution at ClauseElement base

2016-08-31T21:04:35+00:00

Raise a more descriptive exception / message when ClauseElement
or non-SQLAlchemy objects that are not "executable" are erroneously
passed to ``.execute()``; a new exception ObjectNotExecutableError
is raised consistently in all cases.

have it; keep it simple

- Multi-tenancy schema translation for :class:`.Table` objects is added.

This supports the use case of an application that uses the same set of
