Title: Simplifying identation

Using $indentationUnit * $indentationLevel instead of ' ' * $indentationSpaces * $indentationLevel

Additionally, this allows to indent with different characters, like tabs for example. Or in my case, comas or some other delimiter for CSV files.

By default, $indentationUnit is 4 spaces, just like before.
