Removing commented out code

For heaven's sake, I have version control. Why did I ever comment this
out? Merciless removal is my *modus operandi*.

Correcting a typo on Property conversion

I want to make sure that the Property values are correctly assigned.
Removing extra puts command

I was using this to see what the file names looked like.

If the property is initialized with values, I want to make sure to do
this in the same way.

`Property('predicate', [1,2,3])` then the values would be `[[1,2,3]]`.

This may be a bit counter intuitive.
