[JW Lua] Read FileInfoText + Display the value of variable

[Jari Williamsson]

Trying to answer both Bart and Charles in the same reply:

> local title_text = finale.FCFileInfoText()
> title_text:LoadTitle()
> local title = title_text:CreateString()
> print(title.LuaString)

Bart: These 4 lines are correct to get the File Info text for the 
"Title" field and print it. In the case of File Info text, you might 
want to clean the string with "title:TrimEnigmaTags()" as well, 
specially if you're saving it back to Finale.

>                       print(enigmaString:IsEnigmaFileInfoTitle())
>                       if enigmaString:IsEnigmaFileInfoTitle() then
>                             print(enigmaString.LuaString)

Charles: FCString::IsEnigmaFileInfoTitle() would check if the substring 
is the "^title()" Enigma command, which would never exist in File Info text.

Btw, if you use "print(myvar)" and you get the "UserData: 
0xsome_hex_number" output, you'll know it's a JW Lua class. In these 
cases, use "print(myvar:ClassName())" to get the JW Lua class.
