[JW Lua] get all items of "Expression Tool"

[Robert Wildling]

Thank you for your script, Bart Visser! That is extremly helpful!!!

At the moment I am struggeling with getting the text of the Description
field (of a Expression Tool item). The "JW Lua" Class Browser offers a
GetDescription(argString) method (without a return value?), but it
obviously needs a string to do something. Instead, I need to read and
return the Description in order to compare it to another string...

local str = finale.FCString()
str.LuaString = [a variable from somewhere else like "DoubleStaffMMR5"]

... and now?

Any hint would be most welcome!
Thanks!
