/*  Parameters:
            • psVarName       string  Name of the Variable to log

        Purpose:
            • Provide one function to make it easy to log all types of variables, name and
                value, to the Console in a readable format.
            • Array elements are logged in a list

        Programmer's Note:
            • Normally I avoid using the eval() function
            • But this is a simple exception, where there is no other way to
                call the function with one parameter, and log both the name and
                the value of the variable.
            • IMO, the risk of using eval() in this case is very low.
