==== QAS_flushCallStack  ====

This function makes it possible for the script writer to decide exactly when the answer sheet call stack should be flushed, and upon flusing the call stack an array is returned with exactly the same structure as the array returned from the QAS_getCallStack

Furthermore flushing the call stack, will cause an answer sheet context shift to occur, setting the current answer sheet to the initial answer sheet.

'''Syntax'''

QAS_flushCallStack()

'''Arguments'''

No

'''Return type'''

array of answer sheet call stack (exactly the same structure as the array returned from the QAS_getCallStack)

'''Example '''

There are 3 questionnaires jumping from A(6432)--> B(6433)--> C(6458). Users put the following CGS in a dummy question on C
<source lang="javascript">
aray cs=QAS_flushCallStack();

/*returned an answer sheet call stack with 2 stack frames
{90462158,{90462158,90462159,90462160},{{{6432,90462158,D_returnBack},{6433,90462159,Q1}},{{6433,90462159,D_returnBack},{6458,90462160,Q1}}}}
The call stack is flushed, and an answer sheet context shift takes place so that the remainder of the script is executed with the initial answer sheet set as the current answer sheet in the answer sheet context.*/
