This snippet demonstrates the use of the @code{Measure_counter_engraver} to
number groups of successive measures.  Any stretch of measures may be numbered,
whether consisting of repetitions or not.

The engraver must be added to the appropriate context.  Here, a @code{Staff}
context is used; another possibility is a @code{Dynamics} context.

The counter is begun with @code{\\startMeasureCount} and ended with
@code{\\stopMeasureCount}.  Numbering will start by default with @code{1}, but
this behavior may be modified by overriding the @code{count-from} property.

When a measure extends across a line break, the number will appear twice, the
second time in parentheses.
