Why do you need levelWriterAdapter?

[kemics]

Hello,

I wanted to ask, why do you need levelWriterAdapter, that implements LevelWriter, if it WriteLevel just calls the Write io.Writer method with no level usage?

And the second question, don't you think, that in MultiLevelWriter() function it is better to create lwriters with initial length == len(writers)), just like this:
lwriters := make([]LevelWriter, len(writers)) and then add elements by index?

Thank you for your package, it is really nice

New want an io.Writer but if the writer does also implement LevelWriter I use it. The levelWriterAdapter is used here to unify all writers and save a type assertion/condition on each write.

The make([]T, 0, len) with append is equivalent to make([]T, len) with index performance-wise and I prefer the style of the former.
