* 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'.
