Tests the transaction abstraction system.

We test nesting by having two transaction layers, an outer and inner. The outer layer encapsulates the inner layer. Our transaction nesting abstraction should allow the outer layer function to call any function it wants, especially the inner layer that starts its own transaction, and be confident that, when the function it calls returns, its own transaction is still "alive."

Call structure: transactionOuterLayer() Start transaction transactionInnerLayer() Start transaction (does nothing in database) [Maybe decide to roll back] Do more stuff Should still be in transaction A

These method can be overridden by non-core database driver if their transaction behavior is different from core. For example, both oci8 (Oracle) and mysqli (MySql) clients do not have a solution to check if a transaction is active, and mysqli does not fail when rolling back and no transaction active.
