Please add documentation for modifiers. Where are the corresponding values
defined? Is there any reason it needs to be uint8_t instead of int?

I am not sure how I am going to use them yet. The original plan was to use a bit
mask hence why I am using an unsigned int here. But the implementation details
for modifiers is set for next milestone so I wanted to pass on dealing with
them. There is a todo in the impl and I will document what we decide at that
time.

nit: empty line here please. Same in other files

Strange, I have one locally in all files.
