[JW Lua] Iterator for FCNumbers or how to a create a simple loop ?

[Jan Angermüller]

Jari,

could you please add a "standard" loop to the FCLuaIterator class, so 
that for example a simple loop from 1..1000 could also update the 
progress bar ? Not all iterations can be broken down to the available 
Finale elements, although most of them are covered by your supported 
classes.
I thought of the FCNumbers class being filled with values from 1 to 1000 
which is then passed to the iterator.  Something like:

function callback(i)
     ... -- do a lot of processinng
     print(i.Int)
     ... -- do a lot of processinng
end

--Simple loop with FCNumbers
local loop=finale.FCNumbers()
for i =1,1000,1 do
     loop:AddUniqueInt(i)
end

local iterator=finale.FCLuaIterator()
iterator.ForEach(loop,callback)

While writing this, maybe it would also be a good idea to add a new 
method to FCNumbers that would would create a range as above. This would 
reduce the code to:

local loop=finale.FCNumbers()
loop:AddRange(1,1000) -- would do the same as the i-loop above
local iterator=finale.FCLuaIterator()
iterator.ForEach(loop,callback)
