Reference: check_object missing explanation of two params

[adrian-datacamp]

The Reference article that covers check_function is missing explanations for

• state=None
• typestr='variable'

[hermansje]

Thank you for reporting documentation improvements!

The first is the implicit state that is built up by traversing the code (as mentioned elsewhere on the reference page, you shouldn't set it manually).
The second is a template to build feedback messages (the construct 'the function ___ is missing' in feedback could be changed to 'the awesome function ___ is missing' using this parameter).

I'll close the issue once I clarified the documentation.
