Detailed Description

An utility class to coordinate transactions.

This class can be used to create an object that automatically rollback a transaction when it goes out of scope.

When the client has finished performing operations it must explicitly call the commit method. This will inform ScopedTransaction to not rollback when it goes out of scope.
