Document issue report

In Document
I found that the first line of code does not work.

SaveFile saveFile = new Savefile("My new save file");

And in the demo file:

saveFile = new SaveFile(name); which can work good.

I think the documentation should be like this:

SaveFile saveFile = new **SaveFile**("My new save file");

Please check the case of Savefile.
