/**
* @file
* event.h
*
* @brief
* Defines the event_t struct that encapsulates an event.
*
* @details
* An event (i.e. a query) has the attributes defined in the event_t struct.
* The values come from various members of the Session class. This is
* a necessary redundancy for two reasons. First, access to this data via
* the Session class is not uniform; it requires various calls and
* calculations. Look at QueryLog::afterStatement() to see this. Second,
* because the QueryLog object controls the logger classes, i.e.
* QueryLoggerFile and others in the futre, event creation and filtering
* is done in one place (QueryLog::afterStatement()) and then acceptable
* events are passed to the logger classes so that all they have to do is log.
*
* Since this is just a collection of variables, making this a class
* with accessor functions is overkill.
