[JW Lua] Reading measures from parts

[Jari Williamsson]

Jan and Charles,

I'll look into the FCPart:IsStaffIncluded issue you're encountering.

One thing I noticed (not related to FCPart:IsStaffIncluded, but to 
document stability) is that if you call FCPart:SwitchTo() you MUST use a 
corresponding FCPart:SwitchBack() call.


Best regards,

Jari Williamsson
