CLI2: The ::analyze framework is in place

- Now the CLI2::analyze framework is in place, the new implementation of arg
  analysis can be built. This algorithm first stores added arguments as-is, then
  processes them into lexemes, relying on Lexer::Type. Any new arguments added
  invalidate prior analysis.
