Utility function to easily verify the visibility of the 3 columns with less code
@param {object} assert - the assert object passed to the test case
@param {object} oFCL - the instance that is tested upon
@param {int} iBeginVisible - whether we expect the begin column to be visible or not
@param {int} iMidVisible - whether we expect the mid column to be visible or not
@param {int} iEndVisible - whether we expect the end column to be visible or not
