I have a couple of questions about comments or documenting in CWL.
1a. What is the difference between 'doc' and 'label' in CWL?
1b. What are the special cases in which one is better than the other?
2a. Are line that start with hash tags, also comments?
2b. if no, what is the use of hash tags? if yes, whats the difference between a hash tag, 'doc' and 'label'?
