La propiedad @code{measureLength} determina dónde se deben insertar
líneas divisorias y, con @code{beatLength} y @code{beatGrouping}, cómo
se deben generar las barras autoomáticas para las duraciones de barra
y compases para los que no hay ninguna regla definida para los finales
de barra. Este ejemplo muestra distintas dormas de controlar el
barrado mediante el establecimiento de estas propiedades. Las
explicaciones están en forma de comentarios dentro del código.

The property @code{measureLength} determines where bar lines should be
inserted and, with @code{beatLength} and @code{beatGrouping}, how
automatic beams should be generated for beam durations and time
signatures for which no beam-ending rules are defined.  This example
shows several ways of controlling beaming by setting these properties. 
The explanations are shown as comments in the code.
