Printing bar numbers using modulo-bar-number-visible

If the remainder of the division of the current BarNumber by the first argument of modulo-bar-number-visible equals its second argument print the BarNumber.

Useful to print the BarNumber at certain distances, p.e.:

• (modulo-bar-number-visible 3 2) -> prints 2,5,8
• (modulo-bar-number-visible 4 2) -> prints 2,6,10
• (modulo-bar-number-visible 3 1) -> prints 3,5,7
• (modulo-bar-number-visible 5 2) -> prints 2,7,12

    barNumberVisibility = #(modulo-bar-number-visible 3 2)

}
