Detailed Description

This is a helper class to create scoped transactions, when you create a local Transaction object it will automatically open a transaction, you can check if the transaction was created successfully by calling transaction(),

Once this object goes out of scope it will automatically rollback the transaction if the transaction was open and commit() was not called. It helps you forgetting to rollback a transaction in case of an error.
