/**
 * This class can be used to change some behaviors of the framework. Every configurable statement
 * contains a unique instance of this class, so changes here will only impact a single statement.
 * If you intend to change the behavior for all statements, use the {@link GlobalConfiguration}.
 * Initial values for this class in each statement are set from the {@link GlobalConfiguration}.
 * Configurable behaviors are detailed below:
 *
 * <dl>
 *     <dt>nonRenderingWhereClauseAllowed</dt>
 *     <dd>If false (default), the framework will throw a {@link NonRenderingWhereClauseException}
 *         if a where clause is specified in the statement, but it fails to render because all
 *         optional conditions do not render. For example, if an "in" condition specifies an
 *         empty list of values. If no criteria are specified in a where clause, the framework
 *         assumes that no where clause was intended and will not throw an exception.
 *     </dd>
