* Copy test
*
* This function copies a test into the current content tree
* <br/>Example:
* <code>
* $currentContent = new EfrontContentTree(5); //Initialize content for lesson with id 5
* $currentContent -> copyTest(3, false); //Copy the corresponding test into the content tree (at its end)
* </code>
*
* @param int $testId The id of the test to be copied
* @param mixed $targetUnit The id of the parent unit (or the parent EfrontUnit)in which the new unit will be copied, or false (the unit will be appended at the end)
* @param boolean $copyQuestions Whether to copy questions as well. Copied questions will be attached to the test itself as parent unit
* @return EfrontUnit The newly created test unit object
* @since 3.5.0
* @access public
