    \class HbParameterLengthLimiter

    \brief HbParameterLengthLimiter is a class that offers support to insert different types of arguments into a QString.

    Supports upto 9 argument inserts per QString.

    Supports different kinds of indicators that are used for marking where arguments are inserted

        - %x for inserting QStrings, where x is number from 1 to 9 indicating the order in which argumentss are positioned.

        - %[y]x for inserting QStrings, x indicates argument inserting order and y is a number indicating the maximum length

                for the argument e.g. %[10]2 would mean that the inserted QStrings maximum length is 10 characters and that the

                limited argument is the second argument to be inserted.

        - %Lx   for inserting numbers, x is used to indicate argument inserting order.

    Example of how to use HbParameterLengthLimiter:
