[composite] Transferring timesignature to analysis spines

[craigsapp]

Time signatures are not conveyed to the composite and coincidence analysis spines:

**kern	**kern	**dynam
*part1	*part1	*
*staff2	*staff1	*staff1/2
*I"Piano	*I"Piano	*
*clefF4	*clefG2	*
*M4/4	*M4/4	*
4C	2cc	f
4C	.	.
4C	2cc	.
4c	.	.
=	=	=
*-	*-	*-
!!!system-decoration: {(p1)}
!!!filter: composite -ceg

To fix, you need to add a time signature to the **dynam spine:

If the **dynam spine is removed, then the time signatures still will not be transferred:
