BaseYii beginProfile()

Marks the beginning of a code block for profiling.

This has to be matched with a call to endProfile() with the same category name. The begin- and end- calls must also be properly nested. For example,

\Yii::beginProfile('block1');
// some code to be profiled
    \Yii::beginProfile('block2');
    // some other code to be profiled
    \Yii::endProfile('block2');
\Yii::endProfile('block1');

See also endProfile().
