Thanks for starting this up! I've been wanting to get a puffin reader/writer in here for a while now. I've gone through with a bunch of questions / requests etc. But this also needs to have some tests and potentially examples if possible!
Thanks again!

should we have a way to remove properties also? Or a way to clear the current properties?

Added ClearProperties() method .
is there a requirement for removing a specific property ?
