 * CProfileLogRoute displays the profiling results in Web page.
 *
 * The profiling is done by calling {@link YiiBase::beginProfile()} and {@link YiiBase::endProfile()},
 * which marks the begin and end of a code block.
 *
 * CProfileLogRoute supports two types of report by setting the {@link setReport report} property:
 * <ul>
 * <li>summary: list the execution time of every marked code block</li>
 * <li>callstack: list the mark code blocks in a hierarchical view reflecting their calling sequence.</li>
 * </ul>
 *
 * @property string $report The type of the profiling report to display. Defaults to 'summary'.
