Draft inline documentation

This pre-release is primarily for documentation testing purposes, before merging the branch in completely and closing out the related issues.

• Comment out reminders,
  so that authors have to explicitly opt-in
  case-by-case.
• Add inline documentation comments
  (marked with @docs)
  using Doxray
  and YAML format.
• Exclude irrelevant files from npm releases
• Typo fixes
