[JW Lua] Deleting all parts

[Jari Williamsson]

Jan,

Finale doesn't current provide delete of parts to the PDK. From a 
calling plug-in's viewpoint, there isn't any similarity between Finale 
data and parts, they are called very differently. It's just that I've 
tried parts and data to "behave" the same way in my PDK Framework (and 
in JW Lua), with LoadAll() and such stuff.


Best regards,

Jari Williamsson
