Code to know in how many layers an AOT class is being modified

Thank you Jan B. Kjeldsen for the code.

static void UtilElementTest(Args _args)
{
    UtilElements        utilElements;
    ;
    setPrefix('Querying UtilElements...');
    while select utilElements
        where utilElements.parentId == classNum(SalesFormLetter)
        // && utilElements.recordType == UtilElementType::ClassInstanceMethod
           && utilElements.utilLevel != UtilEntryLevel::sys
    {
        info('Name: ' + utilElements.name +
             ', Layer: ' + enum2str(utilElements.utilLevel) +
             ', Object type: ' + enum2str(utilElements.recordType));
    }
}
