[JW Lua] Some staff system metrics

[Jari Williamsson]

Charles,

Use the FCSystemStaves collection class for each system, which contains 
the available staves (and their distances) for a specific system. If you 
already have a FCStaffSystem object, you can use 
FCStaffSystem:CreateSystemStaves() to automatically load/create the 
FCSystemStaves collection.

The Distance property in FCSystemStaff is what you're looking for.


Best regards,

Jari Williamsson
