/**
 *  Base class for CiviCRM unit tests
 *
 * This class supports two (mutually-exclusive) techniques for cleaning up test data. Subclasses
 * may opt for one or neither:
 *
 * 1. quickCleanup() is a helper which truncates a series of tables. Call quickCleanup()
 *    as part of setUp() and/or tearDown(). quickCleanup() is thorough - but it can
 *    be cumbersome to use (b/c you must identify the tables to cleanup) and slow to execute.
 * 2. useTransaction() executes the test inside a transaction. It's easier to use
 *    (because you don't need to identify specific tables), but it doesn't work for tests
 *    which manipulate schema or truncate data -- and could behave inconsistently
 *    for tests which specifically examine DB transactions.
 *
 *  Common functions for unit tests
