Detailed Description

An optional transaction is an object that behave like an odb::transaction if there is no currently active transaction.

If a transaction is already in progress, this object actually does nothing, and calling commit() on it will do nothing.

The goal of this object is simple:

That the same code can either run independently (ie manages its own transaction, and commit() it) or rely on the caller's transaction for operation (ie, persists/update its objects, but let the caller commit()).
